Uhm, I got this strange and weird feeling in the back of my head by
looking at it. 

I think it has my spatial sense go wacko - sensory overload, so to
speak.

Wow. The movement is great. How did you code this?

Hi!

The movement of the sphericon is a combination of rotation, translation and
calculation (bad math - i guess. it's not the easiest way...) in 4 steps.
The movement of the conveyor is just a pigment movement - gradient and
radial - it's a fake...

If you want to, i can post the code. (but it's a little mess...)

Please do. I'd love to see how you pieced it all together.
