Funny Cube

The following script will make the GameObject it’s embedded in rotate on a random axis. It will teleport to a new position and select a different rotation axis every few seconds. It will also sync every frame.

-- From scripting team meeting notes:
--   First use case: Cubespin with random start position, random direction, resets after 10s.
