In the past few years, we have covered plenty of cool motion kettles here. The Kamenstein Tiny Carousel World of Motion Kettle is also worth a look. It is a steam driven kettle that gets moving as soon as you boil water in it. These kettles were made in various designs, including rocket, bee, locomotive, and merry-go-round.
This is the rarest of the bunch in this series. You may still be able to find it on sites like eBay if you look long enough.
