The beautifully fragile item you see above is one of ten pieces of moving sculpture that are currently available from the terribly skilled Mr. David C. Roy. He has been making these spring-powered illusions since 1975, so he has quite the archive going! The website is very well designed, giving us easy access to videos of the works in action as well as a brief tutorial as to how he creates such delightful machines. Despite their uniqueness, they are all rather hypnotizing and all very steampunk!

Thanks to Mr. Owensby for the link!
