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 self-made 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
