Well, it was originally a j-rock karaoke room, which all the staff told us was happening, but when we showed up, they'd closed it and no one was allowed in. Miscommunication somewhere. So instead, the twenty some J-rock cosplayers there had a mini J-rock convention in front of the room, where massive photo shoots, conversations, and just good collection of people having fun happened. A few non j rockers joined, came to watch, took piccies... You can see the results on www.psychoticdoll.com.
Go to the Otakon 2002 section, and pull of the smut fest photos. ^^
