This video is from the 2011 Fanime Masquerade, where there was a sort of high school talent show-like performance section that one skit dominated. The other videos have a few hundred views apiece, but this one? 200,000.
Naturally, it’s Portal themed, as it’s three weeks after Portal 2 is out and I can’t seem to stop writing about it. It’s a live action demonstration of portals in action, complete with GLaDOS voice and Chell body doubles to make sure the portal system appears to work.
Very creative, and I’d now love to see a Portal broadway musical, wouldn’t you?
