http://www.gamevideos.com/video/id/4650 So cool. Also, there was a video released at E3, where portals play a similar role. At one point, you're able to look through a portal and shoot yourself in the head, and in another, you observe a fishbowl, and then walk into a portal that leads INSIDE the fishbowl. Does anyone know the game I'm talking about..? I'd love to watch the gameplay trailer for that again. EDIT: Nevermind, that trailer I was asking about was Prey, which uses portals in a different way.
