Sorry I didn't mention it. I guess I forgot or got distracted or something.
Animethon is one of the few cons with a room completely dedicated to AMVs, so there's plenty of time to do various things. Vlad did an AMV-related game show, where contestants were shown a video and had to answer questions anywhere from "what anime was shown during this lyric?" to "what was the colour of X's skirt?" and everything in between.
