glad you got some rest.
hey, totally unrelated, have you checked out the game "Slower Speed of Light
" from MIT game labs?
it's pretty neat idea and i thought of you when i saw/played it.
as far as a game goes, it's dead simple (collect some little balls as you walk around)
it only takes like 10 minutes to beat.
the cool thing is that it attempts to visualize what it would appear like when you approach the speed of light. (or, more accurately, if speed of light were to reduce to walking speed)
don't let your seizure prone friend see it, though.
