Colourful Geometry

I got this quite elegant shape by shining light through glass as I have done for lots of my other shots. It reminds me a bit of the shape of supersonic shockwaves, just the first think it made jump into my head.The focus is a little out but my camera does sometimes really struggle in macro mode! This was surprisingly hard to take; I had to hold up the glass and shine a torch through it with one hand with the other using my camera, really need three hands for this sort of stuff. Anyway I find something just quite drawing about the shape and colour.
