It’s called Vista Inspirat (http://www.crystalxp.net/galerie/en.id.130.htm). What it does is alters some system files so that your computer looks like it’s running Vista – but it’s still running XP. (It only works for Windows XP, as far as I know). It gives you the toolbar, the transparent window tops, the works. Also, it gives you a bunch of themes so you can get Vista in blue, or in black, or green, or Aero (another style – it’s basically a white-color Vista)… It’s pretty awesome. Best of all, it’s a free download!
