[sdiy] LFO, analog computers

[Scott Gravenhorst]

I am personally afflicted this way, although I do not
have epilepsy, but rather a cousin to it called
"sycope dysrythmia".  Flickering old fluorescent lamps
are enough to do it.  Strobes are wicked.  It will
often make tiny portions of a muscle go twitchy, or
it may just make me irritable.  I hate working in an
office where the maintenance crew ignores the lights...
