and then I've found RealDesktop (contact me for an extracted, virus-free installer), which inspired me on a complete 3D desktop environment (like playing a 1st-person video game).
this can't be done easily in windows, and NTFS killed my HDD, which I'd planned to install linux when it died.
you'll need an overlay window for one (like RealDesktop)
I'm not sure how you could get your windows in a 3D space, but I've used CubeDesktop before and that displayed the windows almost similar to my intentions.
As for RDesk, screw it, here's the istaller extracted from the official adware installer: https://copy.com/kfN9bGHd1xmvgUSj
^any new updates I think should auto-update, don't quote me on that though... heh
