Cube Loop comes from Marcelo Pars. The object is to form paths that connect the start and end points of each color.  I played a game almost identical to this about 7 or 8 years ago. Unfortunately, I don't remember the title.

Cube Loop seems too easy at first because the the size of the cube never gets above 4x4x4. However, I jumped to the last 3 levels, and struggled mightily.
