Nutating Disc Engine (functional demonstration)

A nutating disc engine is a type of positive displacement engine that uses a wobbling disc instead of pistons or rotors. The disc inside nutates - meaning that rather than rotating, the disc wobbles on it's rim like a coin as it dies after spinning on a table.
