Gameplay Monthly offers a ShakyCam video of the Portal 2 presentation at E3, with Valve's Erik Johnson narrating footage from the upcoming platformer, showing gameplay, as well as cinematics. The clip shows the environments of the ruins of Aperture Labs, interactions with a sidekick even more personable than the Companion Cube, a brief chat with GLaDOS, and some new gameplay mechanics with tractor beams, aerial faith plates, thermal discouragement beams, and more. The clip is at an off-angle, but is in fairly sharp focus.
