I apologize that they are all still-frame avatars, I've only ever made myself one GIF avatar. Every single one of these is one that I have used at some point in time.
I used to be on GagaDailyBoards back in its last golden days (I assume it was good before I joined too, or at least they say it was) and used lots of GAGA avatars of course, made some I never used and some I'd be recognized for, even whole sets (with graphic signatures).
