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:

Cutting pattern into each face of the Icosahedron - which is made up of equilateral triangles

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:
