I don't know if you've been following the yahoo group, but I recently programmed an NxNxN simulator. To turn the cube, you just have to drag one of the stickers in the direction you want it to go.
The Computer 2x2x2 UWR was set on my program.
You can find it at http://www.mzrg.com/java/IsoCubeSim/index.shtml
At the moment, I'm working on a feature where you can save, load, and play solves and patterns.
