Wow, I didn't even know Alice was using quaternions!

Quaternions are a specific type of complex number that makes calculating
spherical motion (think rotation of a ball joint) a little bit more
accurate. Check out slerping ( http://en.wikipedia.org/wiki/Slerp ). I would
very much doubt any students using Alice in Secondary or even Tertiary
institutions would require access to the quaternion methods and would be
able to suffice with the turn / roll methods.
