You mention that the ability to hold your *eyes* still is a very rare talent,
yet you want an interface that works by thought?!!  You must indeed be very
mentally disciplined, to never have your thoughts drift while (beer, lake, 
and a...excuse me) sitting at a computer, especially while waiting for a
task to complete. 8-).  I can imagine it being embarrassing if my boss came 
by and saw on the screen what I think about when I *should* be working.  On
the plus side, system security would probably be pretty easy...
