Puzzle, Skewb

The faces of this cube are blue, orange, green, pink, yellow and white. Each face is divided into a central square and four surrounding isosceles right triangles. The puzzle was invented by Tony Durham of England and marketed by Uwe Meffert of Germany.
Unlike the Rubik’s Cube, moves do not rotate a single face of the cube. Rather, each rotation divides the cube into two congruent polyhedra that meet in a regular hexagon. The edges of that hexagon trace the hypotenuses of the right triangles on adjacent faces of the cube. The mechanism used is different from that used in the Rubik’s Cube.
Meffert had earlier developed the Pyraminx, a twisting puzzle shaped as a regular tetrahedron, a pyramid with four faces that are all equilateral triangles, and called this puzzle a Pyraminx Cube. The name Skewb was suggested by Douglas Hofstadter an 1982 article in Scientific American.
