I wrote a trivial program that blinks the screen on and off at frequencies
from 3 to 20 hz. Staring at the screen for a few minutes at 20 hz or more
made me tense. Eight or 10 hz produced a dreamy sort-of-stoned feeling.

All that this accomplished was to show that blinking light could influence
my brain; but I never was able to find any real constructive use for it.
