I haven't the patience to read through this entire thread (and it's like, late, I should totally wrap this up and go to bed...) but this idea is pretty much the type of AMAZING, bring-your-video-camera kinda fun that makes a con.
I am so down with this.
OH, THE LOOKS WE WILL GET.
Random cosplay in public situtations-- I totally do it for those looks.
