You can already do a handful of gestures on the new MacBook Air and MacBook Pro's trackpad, but Apple's going in and patenting a whole bunch more. Not only are there gestures in this application that involve a thumb and three fingers?something casual users will probably never use?but there's even a sample of how this would work for games like Tetris (shown after the jump) or Final Fantasy. Each "chord" would correspond to a character or movement or attack or something, which is definitely not simple like the Firefox/Opera mouse gestures we've gotten used to. Still, more gestures are always good, and we're sure the end product won't be ridiculous like these. [Unwired View via Crunchgear]
