This may seem kind of odd, but what about a room that shows live action anime based stuff?
Like PGSM, and stuff.
I ask, because....well, believe it or not, I actually have a few things based on anime on DVD.
I have both Guyver movies, I have G-Saviour, I have Fist Of The North Star, and I even have Dragon Ball: Let The Magic Begin (IN ENGLISH!). I also have the G.T.O. movie on DVD (I have the eps on DVDRW, so, if anyone wanted to show those, I could at least get them to ya, I also have the Special and movie on there, too), and Crying Freeman.
As for Japanese movies, the only legit copies I have are of Returner and Versus, but I would definantly be willing to loan them to the con, by the way, both of those come with a dubbed version, and a japanese subtitled version.
I definantly think a Live action room might be a good idea.
Yeah, I have an odd habit of collecting live action anime based stuff.
