I have no C programs for the cube but MAPLE has a MAPLE-to-C conversion, but one would have to write their own display. I don't have a 2x2 program in MAPLE but I'm saving that project for a student since it is relatively easy, given that I have one for the 3x3 and 4x4 cubes. > 2.

My programs are simply "virtual" cubes with no brains. Sounds like your program gives the cube a brain! Maybe you could post more details. I don't understand how it works. - David Joyner > Shai > > >
