Pyramids

March 5, 2010

I’ve been experimenting using some good old reflective card to create 3D shapes that could mirror well as collective components to a larger shape.

I started off with just the outer shell and got a bit carried away with this initial shape and how it worked with my reflective pattern sheet:

This is a head-on view looking into the pyramid shell, the inside is reflective the outside just white

This is the pyramid before adding the back panel. The pattern is mirrored in interesting ways. The top bit looks like a scary eye!

Pyramid - top, angled view. Placement of the top of the triangle means the pattern is better tessellated and therefore works better in creating an infinite pattern within the pyramid

Invisible pyramid - reflective panel added to outer wall

This one is my favourite because with the addition of the outer reflectivity an illusion is created whereby only the edges of the 3D shape is visible. The rest of the shape looks like it’s semi-transparent and showing the underlying pattern when it is actually a reflection of the pattern around all sides including the inside. I really like this aspect and would love to play around with it some more if I get the time.

Moving on, I started making smaller pyramids to fit inside the large shell to try and recreate a tesselated look without a 2D pattern.  Here’s how I constructed it:

And here’s a better view of the final structure – a sort of open-ended pyramid filled with smaller pyramids which were also open-ended:

Pyramids!

It’s nothing major and only a small tester model but on a large-scale I think it could look really good. I noticed that with there being gaps between some of the edges it wasn’t such a bad thing as it allowed light to come in through the back and illuminate the inner space and so allowing the reflections,  symmetry and geometry to show more clearly. It’s especially nice to look closely as if being enclosed by the reflected walls and getting an impression you could be encompassed by this structure. If it was life-size, sitting inside would be quite entrancing I think.

In a way it would be really good to be able to create many different pieces that reflect the developments in my research but that would be like setting up a massive exhibition of my own! (Maybe one day)

We still don’t know for sure how much space we get for our individual work in the end of year MA show. I’m hoping to get a proto-type completed soon so that I can not only know for myself what scale would work best but also use the proto-type to indicate scale and usability to others.

Ico(ne)sahedron

Yey I finished it!

It was quite fiddley but I felt like I was in nursery doing crafts again. It was so much fun putting it together. For some reason I decided to make life a little difficult for myself too by cutting a simple pattern into it which took tonnes more time but now you can see how the pattern relates to the shape and also a kind of indication of the 3D structure that forms an Icosahedron.

So continuing from last week the images below show the process for making it:

So obviously as soon as I got that done I just had to start experimenting. I used my reflective sheets and cut-out from a few weeks ago and formed a quick sculptural piece similar to what I would submit for an installation. I laid this flat, turned the lights off and left the small PIR unit at the end of the cone like shape to allow the light to flow through this towards the icosahedron and onto the cut-out pattern below.

Only the PIR light has been left on and creates the view seen here. There is a mix of shadows competing with reflections and larger areas of light and shade.

I like how this looked against the black of darkness. It conveys the high contrast I was after and allows the distinctive shapes to show clearly.  The reflection of light makes it much brighter and the shadows cast from the patterns much darker therefore it stands out with much more contrast and visibility. I also like the fact that the whole piece is surrounded in darkness and therefore allows it to seem like a standalone installation that could fit into a generic gallery space.

In addition to this it looks quite futuristic and space age – not really something I considered before. I may contemplate this at a later stage – whether I want to leave this aspect as it is or change or remove it.

I also realised that the shapes and lines and use of the cone shape remind me of architectural structures. This was reaffirmed when I received feedback in which a similar comment was made.

I don’t think the photos do this piece justice though. It’s meant to be viewed in its physical form with the naked eye. In trying to capture it as an image it loses some of its awe. The good thing about it being a physical and 3D piece is that it encourages the viewer to move around it and explore it from different angles. By doing this the view changes with shapes changing according to the direction of light and casting of shadows and reflection.

I think for this point of the course – with the Unit 1 assessment just around the corner – it’s a good thing I’ve been able to experiment with the shapes and lighting even if it is still only the early stages of this.

The set-up of all the parts and the addition of the lighting meant a lot of time has to be set aside for this in future.

My next objectives are to:

– Do more research into lighting – especially motion sensitive options.
– Look into stronger materials for another prototype.
– And sooner or later I will need to pick my final pattern – which I will need to convert into a vector image suitable for use with the laser cutting machine.

PIR lights

November 16, 2009

The small magnetic lights arrived from Hong Kong but they don’t work all that great. They are supposed to work with a magnet that once pulled away from the unit cause the light to switch on. They are advertised to be used in say a cupboard where the magnet would be attached to the inside of the door and the light would be attached to the underside of the top of the cupboard. So when you open the door the light turns on. However, they seem to be a little temperamental and have either stopped working completely or decide to switch on or off in an erratic manner unrelated to the location of the magnet. They are also actually much smaller than I thought. But then that’s the risk of purchasing something from ebay I guess. They only cost about £4 so it was worth the risk.

Anyway I thought they could be used in some inventive way. I thought of maybe attaching the magnets to wands and getting people to turn the lights on from hidden places under my possible sculptures? Or some other hidden form of physical interaction where the person wouldn’t know a magnet was involved and would just assume it was all touch based. Hmm, if only I could create something touch based – but I’ve realised my skills in programming will not be advancing any time soon.

I’m actually quite wary of even going down that route – not only because I know I am not going to have time but also because I think I can find alternative solutions that allow more time for experimentation and proto-typing instead. Plus the pattern-making takes up the majority of my time. I don’t mind this as I still enjoy this very much, but it means I need to manage my time especially efficiently.

The disappointment of these small lights led me to Maplin where I purchased a much chunkier light which actually uses PIR (passive infra-red) to detect movement and so turns on automatically. This is designed for in-door/garage use and works well for what it is. The light seems to have a bit of a blue tinge to it though.

PIR light

PIR light - you can see comparative size of this to the smaller lights and the small pin I left on the desk but which highlights the scale of proportion

The down-side is that there is no flexibility in terms of how long the light stays on for (dependent on movement being continuous) and it has only 3 modes:

– On all the time,
– Off all the time,
– or automatic activation which only works in the dark and when movement is detected.

I did a bit of testing with this and it turns on as soon as you get a few feet near it. But the light doesn’t reach far enough and this I think will pose safety issues unless I have some other dim but permanent source of light also in the room/space I exhibit it.

During my tests I stuck my reflective cut-out onto the ceiling near a corner at a curved angle so that it looked like a web hanging down.

Shadow_vs_reflection - hanging pattern

Hanging reflective pattern cut-out. This was with the light on - one side shows the reflected pattern and the other shows the shadow - both stand out very well

I then switched the lights off and used the PIR light as if it were a torch moving around with it. The cool thing about this is that it deals with a very strong aspect of the interaction I was hoping for.

(I have a video of this but it’s a bit jumpy and has me having a conversation over it so I need to remove the audio before it can be viewed. As soon as it’s sorted I will post it up so be sure to look out for it as I think it’s come out quite good).

Here’s a shot before I made the video – not the best but conveys how it looks in the dark (light source being the large PIR unit I mentioned above):

Shadow_vs_reflection - hanging pattern

Once again shadow vs reflection - a nice line of symmetry shown here

I wanted the light and work to be affected by the motions of the viewer. Carrying the source of light means that the light is in constant motion and as it reflects off of the surface of the work the projected reflections as well as the shadows are also in constant motion.

SO I think this is a significant development – and although it seems a bit funny when I think about how someone new to the work might view it in a physical sense, I also think it will be quite fun.

So my objectives for the next week or so is to think of ways to present this light source to the viewer, look into how they may use this, carry it, interact with it and what the dangers of this might be (if there are any).

I also need to speak to Andy about how dark I can have the space in which I install my work and what restrictions I may face.

As for the actual sculptural materials – I am currently seeking advice on what can and cannot be laser-cut, what is flexible enough to be re-shaped or moulded after having been cut and how I might be able to mount/display these.

And finally – we have our Unit 1 assessment due in early December which is when we not only have to have a proto-type ready but also have an online curated page which illustrates how we have met the learning outcomes for that Unit. I’m pretty sure the curating part will not be too difficult in terms of finding content, but it will be tricky deciding which posts are most significant in conveying my developments. This will be the true test to see if all my tagging and categorisation was done well.

On an unrelated note but one that is concerning me is that I realised I didn’t put enough quotes in my essay. Actually I am shocked at the lack of them and can only imagine I was out of my mind at the time not to have done so. Now I just want to hurry up and know my marks so that I can stop worrying and move on.

Further experimentation

November 8, 2009

Guess what?! For those who haven’t heard, we didn’t get to do our presentations in the end. Just a few minutes before we were about to start we were asked to evacuate the building because of a suspected gas leak. I swear it wasn’t a set-up 🙂

I wasn’t as prepared for my presentation as I would have liked to have been anyway (having been ill the night before) so maybe it was fate. We were not able to get back into the building for the rest of the day so I went home to finish my large reflective sheet cut-out.

Here are the pictures of the final stages of this:

Cutting completed - my A4 cutting mat looking very small in comparison to the A2 card

Layering reflective sheets

Here I layered the cut sheet on a regular sheet of reflective card - already the effect of the lighting can be seen on the wall next to it. I also like the fact that it looks like the reflection is coming from a pool of water

Projection with reflected light

By slightly curving the sheets the projected pattern forms wave-like shapes and also reflects the light at sharper angles. The layering combines the reflection of both the cut-out pattern as well as the blank sheet beneath

Layered projection

This time I placed the top sheet facing down - the effect creates a more solid pattern as this blocks the reflection from the bottom layer

I’m really pleased with how these reflected patterns have projected. My next mission is to find a way to animate the projection – if I can. The curved shape reminds me of waves or ripples and if I can get the sheet/s to move in a similar way then that would be really cool. I can just imagine some kind of handle that you would turn in a circle to get the wave into motion but I have no idea how I would build it. I guess its to do with mechanics and carpentry? I can imagine it being like an old wooden toy. However, it’s not a digital solution which is what I would prefer, but does it matter?

In my workshop this morning we looked into Arabesque, Islimi, biomorphic patterns. These terms are only slightly different in meaning but can generally refer to the same type of floral nature representative patterns. Adam Williamson (see his web site for an idea of his vast skills in this art, including hand-carved stone and murals :  http://www.adamwilliamson.com/)  is teaching this part of the short course. He  showed us a few slides of wave formations and diagrams that illustrate the movement of water behaving like a spinning spiral and the same can be seen in a vortex. He also showed us this video of Reuben Margolin who builds kinetic sculptures that recreate natural movements found in waves and even caterpillars: Maker profile of Reuben Margolin

Just a coincidence?

Nb: one of the first machines shown in the clip is the handle being turned to make the wave motion – that’s exactly what I was thinking!

Reuben Margolin - Kinetic sculptor

Still from video by Make Television on Reuben Margolin's Kinetic sculptures. Here you can see the wave in motion being turned using wooden handles

How am I going to make that? lol I think it would be a tad bit too ambitious to even go there. But I do need to keep thinking and experimenting to find alternative solutions…

Reflective light projection

October 25, 2009

I wonder if the title depicts what I actually mean by it. Well images are always useful in these circumstances. I’ve been to the art shop recently and, as mentioned in a recent previous post, I decided to pursue the idea of using reflections. I found some reflective sheets of card (quite large A1 size) and had one placed on a box in my room lying flat but parallel to the wall. The light in my room was hitting off of the sheet and this was bounced/reflected on to the wall where it was casting some oddly shaped lines.

I then placed a cut-out pattern directly on to the reflective card – that was a good move. The card was slightly curved and as a result the light and pattern was also curved in its projective state on the wall.

I moved the sheet slightly higher and deepened the curve and the results changed too:

I was pleased to see how the small changes in the curves and placement of the card could create many variations of patterned shapes. This led to another few sample work ideas for installation pieces. These would probably be stand alone pieces as part of the wider range of work presented.

I then pulled some of the above photos in to Photoshop and experimented with colouring and was able to produce a hightened contrast by darkening the images and layering and rotating them. The light stands out better here and looks like a hologram or a laser display:

General Update on activities:
I have also been able to find some 3D geometric template sheets online to cut out and assemble. These are small and tricky to stick together but I managed to get them to hold for a few seconds while I took a couple of images. The really hard part will be figuring out how to apply a pattern to these shapes that has a similar underlying grid to the shapes they are made up from. For example for a dodecahedron there will need to be a construction with a pentagon tiling and for the icosahedron an equilateral triangle.

I may need to create a large-scale pattern on a large flat sheet first and then outline the template to cut out from this with correct placement and hope it sticks together right. In practice I will probably get it all wrong – still, no harm in trying.

Pattern-making workshop
I’ve joint a 10-week workshop where we are creating traditional Islamic patterns being taught by Richard Henry. He teaches with Birkbeck as well as with schools and also creates artwork himself. He was also taught by Keith Critchlow so I think we’re in good hands!

Richard’s worksheets are very easy to follow and start from basic circle formations to developing full pattern constructions. Some of the patterns are similar to those I’ve done already but Richard’s approach to constructing them seem easier and sometimes more practical. I wanted to take the class to see how things could be done perhaps with short-cuts or to make some of the stages quicker with ‘best-practice’. Many a handy tips have been passed on already. It has also affirmed some of the general things I’ve picked up about pattern-making and the things I need to be aware of (for example I thought it was just me when my compass would slightly alter itself). All in all I’m really enjoying it.
