Here is a small application I wrote from pure boredom and curiosity.
It is a pathetic attempt to simulate a dream machine. It is supposed to
provoke hallucinations by stimulating the optical nerves with a specific
frequency. That simulation can alter the brainwaves and make you see
complex patterns of color behind your closed eyelids.
Did not work for me – might work for you.
I’ve read an article on this topic some time ago and got curious. I made this stupid application to give it a try.
