Have you ever played with a Rubik's Cube? The six-sided 3-D puzzle caused a global craze more than 20 years ago in the 1980s. New 3-D puzzles, which take the original Rubik's Cube idea into new territory, have now been developed and are gaining fans.
Launched in the fall of 2008, Rubik's Mirror Blocks is different from the original cube in two ways. First, all of the pieces are the same color (silver). Second, the pieces are not all the same size. When you rotate the cube they begin to jut out in places. The more you twist, the further away from the original cubic shape you find yourself.
