I can only guess this player isn't rotating the pieces because he's afraid he might touch the cosplayer's nipple. Or that he'd like it.

GoNintendo found this vid, shot last week at Ohayocon, an Ohio cosplay/gaming convention. I'm guessing the working N-Gage cosplayer was too wide to get through the door.
