This one is for all you Steampunk fans. While there are no gears in this image, the coppery color lends it a bit of a Steampunk vibe, yes?
Honestly, I was just playing around with Silk (see weavesilk.com) and this “happened”. Not quite all by itself, mind you. Once I saw a hint of the potential, I was able to get this to come out. Lovely, isn’t it?
