If PowerPup might once more permit me to use his topic for my programming blog, I have now finished the Cube! It's even better than the Windows version, particularly seeing as I could make it so you could drag the cube, rather than have to click separate buttons (Macs are easier to program than PCs). The two things that it lacks are:
-Colour (OK, I could use Colour QuickDraw, but I'm too lazy to figure out how),
-True 3D display (you can only have orthographic display because I couldn't figure out the calculations for two-point perspective).
But it's still better than the Windows version, even though you can't save the cube state (I haven't figured file handling out yet), or added a solve function (I felt a bit sorry for my poor Mac's CPU trying to do such a big task).
