iGoogle.com

iGoogle is a cool website that's kind of like your own website (well... maybe just your own homepage), you can personalize it with tonnes of all sorts of little gadgets including games and I just so happen to wield two of them; Super Crazy Guitar Maniac 2 and that hamster one I've got on my homepage. Unfortunately you can only use it properly with a gmail account which I have obtained quite a while ago so I have access to the privilages of Google's wonders.
