Epic Empire talk about how CrystalXP has created a vista look-a-like theme for windows xp. So, if you want to experience the vista look now and cant wait for Microsoft to release it next year. Well you need to join the club but you can alleviate some of the pain and frustration during the waiting by having a theme that looks like Windows Vista.
