I'm really looking forward to getting a Leap Motion device! I think there's a lot of possibility there for programmers that are interested in building a new input method.

My thinking is that a Leap Motion could be used with a standing desk (my current preferred desk setup), in combination with existing keyboard and mouse, to replace key combos to the OS like switching windows/tabs, window management (maximize, minimize, expand to left half of screen, etc.) as well as macros for common commands we type all day (`git push` or running the tests, for example.)
