I found something kinda neat. I was browsing around a mac emulation site and stumbled across this http://www.osx-e.com/downloads/appli...s/topdesk.html
From what is shown in the screenshot it works a bit like windows flip 3D in AERO. I haven't tried it but let me know how it works if you download it!
Desktop: Dell Dimension E510, 2.5GB RAM, Intel P4 3.0GHZ, 250GB HDD, Windows Vista Premium. Might not be the best, but the old girl is still running good.
