This is an old optical illusion. It is not really hypnotic, but it uses some of the old tropes associated with hypnosis. Give it a go . . . digital trance hypnotic drug experience without the drugs.

It can be fun.

If you listen to a hypnotic induction while looking at the pattern, you will find it even more powerful (for instance, try it with the eye fixation induction at DRTRC . . . do NOT listen to the files streaming online, download them to your own machine, my server sucks so if you get a timeout or error message that means there are too many folks using it at one time, just try again later).
