[Papervision3D] stumped recreating multiple axis rotation of rubix cube

[nroberton]

Hi, Speedok. It looks like you accomlished exactly what I am trying to do. I
can't tell for sure if yours is really 3D, though. Why is it that it doesn't
rotate during gameplay?

I don't suppose you can share the source?
