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.
