I think future desctops wont look crystal or aqualike, they'll look clean minimalistic but good
My desk is very BeOS-like but I don't want to copy it I only think that the BeOS icons are simple, they represent for what they stand for very good and they look good of course too.

Wallpaper: none just used a blue I like
Icons: Wasp Icons (Very good Icontheme)
Windeco: bII (Very practical cuz u can always see all windows (it aligns them))
Style .net-style also called dotNet
