Pyraminx

A Pyraminx is a variation of a Rubik's Cube in the shape of a four sided pyramid, or tetrahedron. It was invented by Uwe Meffert in 1981. It normally has a color scheme of scarlet, blue, green, and yellow. This puzzle has 14 pieces: 4 centers, 6 edges, and 4 corners.

Master and Proffesor variations have been made by Meffert too.
