Dodecahedron

For the optional theme of "Geometric" I found this cube on my desk in the living room. Not sure whether it can be called cube.
It is 3x3x3 Pentagonal Speed Cube Dodecahedron, also called Megaminx, based on the Rubik Cube.
I don't know how hard this is, but you can learn to solve it quite easily (IMHO easier than the regular Rubik Cube).
