If you are a SL user, and a Weblin user (should really do a post about weblin one day…) There is a great technical project, that allows you, really easily, to turn your SecondLife avatar into a Weblin Avatar.
In a few simple clics, you’re put onto a stage where some very polite but not very talkative avatar comes and takes your picture in a load of different positions. It’s then automaticly transformed into a 2D sprite and associated to your weblin account as one of your animated avatars. It works very well, and is totaly free 🙂
Here are a few photos of a try I did.
