Today's day and age introduces something on a whole different level. Puzzle designer Oskar van Deventer has created the 17x17x17 Rubik's cube.
What I can't get over is how many different possibilities there are. The original Rubik's cube has 43,252,003,274,489,856,000 (about 43 quintillion) permutations, and that's just with a 3x3x3 cube. Imagine increasing that to 17x17x17? I was going to try to do the math, but I gave up.
