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.

It’s not great but I hope it illustrates some of what I was trying to explain in my previous post in regards to experimenting with light, shadows, reflection and the patterns. Just to remind you it’s the PIR unit I’m using as the light source and it turns off when it cannot detect movement hence it going dark a couple seconds into the video:

Excitement begins

October 3, 2009

I am experiencing a surge of brainstorming (I am told this is no longer a P.C word but I can’t remember what the new term is so no offence to anyone) in relation to the work I must complete by December for my assessment.

We’ve been told we should have something along the lines of a proto-type complete for that stage in our course but with all these new and exciting ideas I want to have more than just one project outcome.

I am very excited about creating the physical pieces that reflect the research I’ve been doing for the last year and have been particularly thinking about the space in which my work will be displayed,shown or installed.

There are many different ways a person can present their work and these have inspired me to think of all alternatives – not just as Plan B’s in case my main work doesn’t turn out how I wish but also as accompaniments.

At the moment I am contemplating having 3d shapes with patterns either on, around or made up from the patterns. It’s hard to explain this so I’ll leave it to when I have some pictures once I get experimenting with the shapes.

I have been doing some very bad sketches in my notebook in order to consider how lighting needs to be placed within a rectangular room for example. There also the need to consider where a person might enter from and how they may navigate through the space according to what first comes into their sight. This is very important because I am planning to have my work illuminate itself based on the viewer’s movement into the space. They need to be able to see where to go for safety reasons but it also needs to be dark enough for the light to make the right kind of effect when it comes on. I also need to consider if my work will be one large focul piece or made up of three or four pieces.

These sculptures/shapes also need to fit to either the walls, floor or ceiling but with the light source either pointing towards or from behind them. Once again I won’t know which is best till I try it out. The light source itself is also something I am looking closely into. In my last tutorial Andy and I discussed sensor activated lighting and he agreed this may be the right thing for me to use. I’ve had a look at PIR lighting products and am trying to find something wireless which would be less of a safety concern as well as less shabby looking once up. Pricing is also a factor and how it might be fitted to walls/ceilings.

Another really cool idea I had was to have a sort of very large 3d hollow shape, perhaps made from card or papier mache (or maybe something a bit like stiff canvas or whatever is used to make lampshades), hanging from the ceiling but high enough off the ground to allow someone to pass under it. As they would come closer it would light up and then they would be standing beneath it. When they look up into the work they would see layers of shapes cut into the material and these would overlap so that the shadows and holes would create an ever complicated pattern. What I imagine in my head certainly looks quite spectacular. I wonder if I can actually achieve it.

It reminds me of the Muqarnas found in many mosques around the world, some of the most famous being at the Al-Hambra in Spain and at the Imam Mosque in Isfahan, Iran as seen in the image below. It is a very interesting architectural feature which I will just show you instead of trying to explain:

And yet at the same time what I have imagined also reminds me of a kaleidoscope. As my youngest sister was sitting next to me as I jotted this down I asked her if she knew what a Kaleidoscope was. She’s ten years old and, well, her generation is quite different to mine so I can well imagine that they aren’t likely to be as familiar with a non-electronic/digital toy such as a good old kaleidoscope. And I was right, she didn’t know what it was so I did a quick search and had a look through google images as I explained it to her. I then came across this very interesting image of a human mirrored kaleidoscope:

These kids are clearly having fun, and it means they are engaging with the space too. The effect is brilliant and I think if I could adopt this in some way but have my patterns in there too then it would just be sooo good. But I’m not sure if it would be over ambitious for me to go down this route, least of all because I’d have to actually build an enclosed space with mirrors inside. Or maybe I could make a cheap and tatty/plasticky version? We’ll see. But the use of mirrors is certainly worth keeping in mind.

All in all I am really getting into this and I knew it would be the stage I would enjoy the most. I may be thinking about some of the aspects of the installation a little to early but this is how I have always worked – I like to get down to the nitty gritty much in advance so that I have contingency time as well as other work in place if needed.
