Rubik man

The Rubik’s Cube is a three-dimensional mechanical puzzle invented in 1974 by the Hungarian sculptor and architecture professor Ernő Rubik. Rubik originally named the toy the “Magic Cube” and licensed it in 1980; it achieved unprecedented success, starting in Germany. I also possess the skill of—and demonstrate—speed-solving 3×3, 4×4, and 5×5 Rubik’s Cubes.
