Rainbow gears

This rather abstract image is actually made up of two pieces of plastic (in this case camera filter caps) placed between two polarising filters. The colours are actually a natural side effect of this, showing the stress lines in the plastic in a spectacular way. I actually took a similar shot when I was 15 or 16years old, but I never reshot it again because I don't own TWO polarising filters. However, a chance discovery by my colleague Chris (see link to his blog on the right column) made me realise that an LCD panel can also be a huge source of polarised light (LCD panels work on this same principle, in fact) so with my LCD monitor as a background, I screwed a polariser onto my camera and took a cloesup of these filter screw covers.
