once you have the macros to turn the faces, simply run that macro with some
random parameters about 1000 times to shuffle the cube and keep it solvable. I
agree that it would be easier to grab a real cube, scramble it, and plot out
the moves to solve it. That's quite easily done. Does anyone remeber how to
solve the cube?

So you have to
