To view properly: use anaglyph glasses (red/blue or red/green) and view with red filter over left eye.

Anaglyph stereo of a 120cell in smooth rigid rotation in four dimensions. The 120cell is the 4D analog of the dodecahedron. The apparent distortion is an artifact of the projection from a higher dimension. This is similar to the shadow of a ordinary 3D object changing shape when the object is rotated, even though the object itself might be perfectly rigid.
