There are all kinds of motions to perform different actions--pulling down from the top brings up a menu, moving your hand in a circle changes the volume (clockwise for volume up, counterclockwise for down), that kind of thing. It works with a bunch of different apps, as well. Fruit Ninja was in full effect, working almost as fluidly as the version on Kinect. The rep was an expert at it: judging by the way he was using the system, the thing is impressively responsive. But he wouldn't let me try it, saying that there's "a bit of a learning curve." And when an inexperienced rep tried it, he had trouble with the "grab to select" motion. Still, if they can iron the kinks out, I like the LG version a lot.
