Found this at WinExtra over the weekend, and was only able to check it out recently. XPize is a project to, non-destructively (I hope), make XP look better. Basically they patch some theme DLLs, replace some resources (like all those icons in windows that have been unchanged since the Windows 95 days) and generally tweak a lot of the display. The screenshots on the site give you a good idea on how things look, and point out some of the "problem areas" that this little app aims to tone and sculpt. So far (10 minutes or so anyway) this look good, feel slicker and better, and don't make me want to go against corporate policy and install Windows 7 quite as much :)
