De screensaver Hypercube uit de xscreensaver-collectie toont net zoals Hyperball een geanimeerde projectie van een vierdimensionaal lichaam, in dit geval een hyperkubus:

In de documentatie staat (cursivering van mij):

This displays 2D projections of the sequence of 3D objects which are the projections of the 4D analog to the cube: as a square is composed of four lines, each touching two others; and a cube is composed of six squares, each touching four others; a hypercube is composed of eight cubes, each touching six others. To make it easier to visualize the rotation, it uses a different color for the edges of each face. Don’t think about it too long, or your brain will melt.
