Read full description

This application exploits multitouch controls to explore a hypercube labeled as a 4-dimensional, 8-sided die. The hypercube's eight cube-shaped faces are rendered as a 4D being would see them in 4D light: thus, only one, two, three, or four cubic faces can appear at one time while the die rolls, but no more. Faces that would be invisible to a 4D gambler cannot be seen without interactively rolling the die to bring them into view.
