Had to add my own contribution to the massive amounts of Vista themes. Hope you like it, dont flame me too much!
Should be lightweight since it's under IceWM (about same resource consumption as Fluxbox). Use as Window decoration or as it's own environment.
Please let me know if anything doesn't work/looks bad/needs fixing/etc.
Update 1: Removed transparent pixmap as border, found a workaround.
Fixed corner size so it displays the corners properly
Also, sorry for low quality screenshot, 300kb limit is a bit harsh on a 1600x1200 image.
