Hey i have been trying out some cool skins lately and i recommend you guys to try them out. The most amazing one i liked and i guess some of you who fancy crazy hacking like, computer based things, which is a great one to try is The Alienware Invader from http://www.skinsfactory.com. Then if you enjoy that try out the other new Alienware releases such as DarkStar from the official Alienware Website, (hard one to navigate around lol). They also supply desktop themes which unfortunately didn't work for me since i have vista. In addition the Microsoft website also has a few cool skins, search for "T3" , a terminator 3 based skin that i currently use and prefer.
