Unicycle
This is my unicycle test. Everything was built as NURBS because...it seemed like a good idea at the time. The unicycle was built in a hierarchy so that as the wheel turned (or as the seat post leans forward or backwards), the foot platforms of the pedals remain parallel to the plane of the seat. Also, there is a modifier on the bottom of the wheel that squishes it, as though there were weight on it, that stays directly under the hub of the wheel and on the ground as you rotate the wheel and lean the seat post. The rotation of the wheel was achieved by a script that looked at the change in location between frames and automatically rotated the wheel to achieve the same distance. Unfortunately, I have no idea where that script is anymore (I thought it was saved in the file, it does not appear to be so).
