well normally the brain works at a frecuency of 20hz

at five hz you fall asleep

at certain frecuancies you can induce moods as happyness or euphoria

well it would be extreamly easy to make a small basic program in which you have a blck-white screen flickering and with a couple of keys you control the frecuecny of flickering

so you would start on 20 hz flickering and as you feel your brain respond to the signal reduce it to induce medidative states

i had this idea months ago, discard it as totally nuts then

but well its the same than binaural beats with vision insteda of sound

in fact i bet they may sell this stuff quite expensive i rememebr binaural beats program offered buy light alternatives

btw i think it should be mandatory beofre you drive a car beeing under a flashy light as an eppillepsy test
