Twitter by it’s very nature is a very limited service. That’s what’s fun about it. Some people manage to be really clever and witty in 140 characters. But there’s only so much you can express in a tweet. The other main way to express your personality on Twitter is through your avatar image (or ‘profile picture’ as Twitter calls them).

Many of the people I follow have carefully designed avatars that they don’t change very often. But what if you could have your avatar be as current as your tweets. Showing you exactly the way you look today, doing what you’re doing right now? That’s where Snapatar comes in.
