I haven't seen this in the stores but there's a new accessory for playstations that gives them visual input. The NamTai EyeToy camera watches the player punch, kick, or wiggle fingers and uses the actions as gaming inputs. There's a brief teardown article over at EETimes.
This might be fun to experiment with as a UI interface. Instead of hitting a function key to have OS X reveal the desktop (or click the desktop icon in XP) you'd wave a dismissive hand across the screen. You could assign a whole array of shortcuts to interesting hand/finger gestures. I already know what finger gesture would work best to dismiss the office paperclip!

Your welcome
Sounds like you're on some good medicine, anyway. ;-) My S.O. just returned from a long day at her work, and appears to have picked it up, despite flu shots...I'm next, I presume...
Nixon hallucinations are part of the package...no medication required!
Good luck! At least you'll be able to catch up on restless, dream warped sleep...
