G, E, B, Leviathan

The shadow of this cube in different directions gives QR codes pointing to the Wikipedia articles for Kurt Godel, M.C. Escher, and J.S. Bach respectively. Note that QR codes cannot be read in mirror image, so only 3 of the 6 possible cube orientations cast a readable shadow.

Best comment:

"Though it's true QR codes can't be read in mirror images, these particular reverse images codes do work. They point to the Wikipedia articles for Achilles, Tortoise and Crab."
