13x13x13 Speed Cube

This can’t be called a Rubiks Cube, primarily because a Rubiks Cube is fun. There’s also the matter of trademarks, but let’s be honest: this isn’t fun. Memorizing and then repeatedly applying algorithms on a $300+ piece of plastic can be described many ways, but “fun” is not one of them.

On the other hand, if fun’s what you’re looking for, go for the 11x11x11 Speed Cube. That’s some good ol’ fun like Grandpa used to have. Smoking a pipe on the porch, whittling an 11x11x11 cube out of some fine plastic, covering the cube with “some type of goo”… none of this newfangled junk.
