I have uploaded a demo to my dropbox:

http://dl.dropbox.com/u/5000845/Rubik%27s%20Cube.rar

In this demo you can just play the cube and win(or not :P). You can switch the cube resolution. The other things, like saving/loading and the skin editor aren't wokring perfectly, so they are not included

I really wonder how the rar can be so small, while the models are about 400 mb - lol - the rar is 5 mb

Have fun and please report bugs

Oh, and i also have a ToDo more - if the block is in a non x*90 angle, the clicking still works with up and down / right and left - but you will see
