Okay an idea. I know one OS has something similar to it basically you make a desktop, 6 times. And then put all the desktops in a 3D Cube. Then you makie it so users can flick around the cube on say the click of a button, or if you drag your mouse in that direction etc.

I think its Linux that has this. Doesnt have to be the size of the screen though. Make it like half the size and center it. So its like an actual cube on your PC.
