Create beautiful avatars for Twitter and IMs with FaceYourManga (#)
Yahoo has had its avatar creator for quite some time, as have so many other services. However, there is a new cool kid on the block: FaceYourManga.
FaceYourManga creates avatars through a multiple-step avatar building process, configuring everything from face, color and nose to hair. Finally, you can enter an email address to get the avatar emailed to you. Perhaps, the only thing they should improve on is page load times - it felt a bit slow at times. Every time you click on a customization, it takes time to redraw the avatar, which I think is unintuitive.
