I had a random moment and came up with a design and kept messing with it. This was the last point at which it looked right, before messing it up with further tweaking.
This looks like a tangle of chains in a jewellery box. You know the way they seem to tangle and knot however carefully put away? So the resulting mess makes you wonder how many are broken, how many can be reclaimed whole and how on Earth you are going to de-tangle them to find out?
I'm not sure I'd like this on the desktop - though it is hard to say - but it is certainly very interesting.
