We had to do these on at our cinema as well, to see A Christmas Carol in 3D (which was kinda okay, I guess). €50,- a pop, so about $70,-. They're not very comfortable =(
Projects like this make me wonder though, why hasn't Nintendo made something like this yet? I know a lot of people who'd buy something like this, I bet there has to be a market for it.
Maybe something to implement in the next generation handheld, Nintendo? Pretty please? #portablegamecube
