I don't think anything like this has been done recently and it's only a bit of fun.
Basically, on every forum I frequent, there are always a few people with really annoying animated avatars that are either set to loop too fast and just about give you a seizure when you see them continually out the corner of your eye, or are just annoying like the Crazy Frog inspired ones I have been seeing around recently.
Anyway, you can nominate people from Minitokyo here and remember, it's not abusive, just fun ^__^ .
