sure, that clocky thing would be neat.
but how much cooler would it be, if instead of that contraption, you
had one of those little air hog indoor r/c helicopters.
it could fly on a couple of preprogrammed flight plans and potentially
get a little buzzer.
you could even sell replacement helicopters since dogs, cats and tired angry people would catch them and throw them.
think about it, how pissed would you be if a buzzer was flying around in the dark, and you could not get it?
