Well, I thought maybe it would be clearer if it rotates (in 3D).
Again, sorry about the horrible things MPEG did to my video. (Oh yeah -
and the floor/wall textures. :-S)

So it rotates in the x-y-plane (I guess a rotation can't by defined
by an axis in 4D). I wonder what it would look like it it did
rotate in the x-w-plane...

Yup. In 3D, a normal vector defines a plane - but in 4D it defines a 3D
volume. So yes, you have to define it by plane rather than axis.

Just for you... see my next post. (I wasn't gonna post this one cos it's
not as interesting to look at, but since you asked nicely...)
