The fancy "In Motion" DLC for the PlayStation 3 version of Portal 2 is available today.
We last saw "In Motion" at E3 this summer, where a Sony representative demonstrated how the Move works with the Aperture Science Handheld Portal Device. The DLC adds new kinds of controls to the game, including, notably, the ability to scale a cube in size while holding it. (Just when you thought you had mastered thinking with portals, along comes a whole new mechanic to trip you up.)
The "In Motion" DLC also includes new levels to go along with the new controls, and that, of course, require features like portal surfing and item scaling to solve.
