Rubik's Cube, named for its inventor Erno Rubik, is also called the Hungarian Horror, since it can induce temporary dementia. It is a brightly colored cube, the faces of which must be aligned to make a solid color-one face red, one yellow and so on. The aim is to scramble the colors and then manipulate them back the way they were. The number of potential color patterns: well over 43,252,003,274,489,856.
