I first saw a "clockwork insect" in my professor's office two years ago. I've since noticed them at steampunk fairs and online, and I think they're really beautiful. It makes a great conversation starter, and can even give rise to philosophical debate. And if you're very careful, you could turn it into fascinating jewelry!
I didn't have any immediate plans to make one of my own, but when I found this beetle dead but intact on the side of the road, I knew it was time to try my hand.
Step 1: Materials
Beetle (find a dead one?)
Clockwork pieces (you can get these really easily on Ebay)
Black fabric (to lay out gears on)
