In a non-English magazine a scientist said that very little is known about the relationship between the light and the brain. He proceeded to say that it's interesting how the lights going on and off influence the brain. He claimed that when the light goes on and off extremely fast (more than once per second), that creates resonance with certain waves in the brain. Specifically, he gave the folowing examples:

~7 times per second resonates with theta-rhythm. It influences the brain by inducing a state of "oceanic feeling" (the feeling of no body, the disappearance of the definite "me").

10-14 times per second resonates with delta-rhythm. That can induce visions.



All that sounds a bit alike the idea behind the binaural beats, but in this case the resonance effect is achieved with the light going on and off extremely fast.

That makes me think. Some binaural beats are supposed to make you LD or OBE. But I heard that they play the frequences of sound that normal headphones cannot play, which can account for failures. With light it's a different case, it can be done, as there are no such hardware limits...

So what I have in mind is a kind of a computer program that presents only a black screen, and then can make the screen blink a certain number of times per one second by filling it with white color. If it does it in a continuous manner, this program would fully make up for lights going on and off, if it is used in a dark room at night.

Is anybody interested?

Does anybody have programming skills to write such a program?
