I've been fooling with CSS filters a little lately. I know they're proprietary, but it would be really wonderful if they make it into CSS3 (even by different property names and/or possible values). Anyhow, in case you're interested, here's a link: http://msdn.microsoft.com/library/default.asp?url=/workshop/author/filter/reference/reference.asp and be sure to click the Show Me button on that page. It opens a new window where you can fool around with filters all you like and see them in action. Have fun!
