I wanted to make a teapot that would work but incorporate a few mechanisms of some sort. The result is this.

The teapot itself is ceramic and took the least amount of time to make. The undercarriage is made up of some skateboard wheels I had as a kid. The base frame is scrap steel from where I worked at the time. Most other bits are from laser printers and the like. The hub upon which the tipping yoke sits was made from melting down old soft-drink cans and doing a sand casting.
