After many years, I have go to say...
This video is honored to my dear son, unfortunately he's lost one eye because of disease.
3d is not our nature, we can see even more by our brain. It is a trick.

The 4d cube/tesseract rotation, perspective projection, unwrapping from 4d to 3d and wrapping back to 4d.

This is a projection of tesseract into 3D space. Here presented only vertices, edges and faces.So to imagine a 4D cube, we must also see a volumes. It is difficult because off it is not a 3D model in 3D space, it is a projection onto the flat 2D screen of your device.

All computations and visualization done with aid of selfmade 4d library for PovRay (http://povray.org)

May be someday I make a 3D version of this animation...

There are many questions about the music, so here is a link
