Colorful Tesseracts

Edited Internet Archive book illustration with lots of prettily-colored cubes. Actually, the book is on tesseracts (four-dimensional cubes) and the color are intended to help visualize them. The color didn't help (at least for me).

 

A four-dimensional cube (the tesseract) would have as its shadow a three-dimensional cube (just as a square or parallelogram is the shadow of a cube) so when you pick up dice, you're picking up tesseract shadows. (Probably not really, though... It's dangerous to reason by analogy (but easy and fun!).)
