I found this yesterday. Seems to be a very exciting new way to look at and work with XP (or Vista). I don't know how reliable it will be but i love the graphic/operational design.
Looks okay, but my jaw dropped a couple of days ago when I saw a screenshot of a 3-D desktop where the icons were like tiles scattered about, with some piled atop each other like dominoes. Now I can't remember where I saw it, but at the time I thought to myself, "Cool!"
