If you are jealous of your geeky linux friends that have Beryl running under linux, you should check out Yod’m 3D, a small application for Windows XP / Vista that will give you a decent substitute for the “Desktop Cube” effect.

If you want each desktop to have it’s own wallpaper, you can change the wallpaper for that desktop by switching to the desktop and then set the wallpaper the normal windows way.
I found that the transitions are just a little bit slow (especially on older hardware), but tolerable. I probably wouldn’t use this on a regular basis, but it’s a nice piece of eye candy to show off. Note that this is the same guy that made the Visual Tooltip software I wrote about before.
Update: This software is no longer free. I’ve updated the link to the new site
