Google launched a new service today called Lively, a browser based virtual world add-on that lets users create and customize avatars and worlds and interact with other users in these rich environments.

Elegant, intuitive and well executed online application for generating your own grid-based fonts. There's also an extensive library of previously created fonts available for download - some of them are fantastic.
Ffffound! is a web service that not only allows the users to post and share their favorite images found on the web, but also dynamically recommends each user's tastes and interests for an inspirational image-bookmarking experience!!
