This program uses stereo sounds (So you'll need stereo headphones) to alter/create brainwaves for a certain topic, i.e. Inducing sleep, boosting creativity, boosting intellect, or even causing pain. I've found the creativity booster useful! It could just be suggestion... but it could not! Try it - I dare you.

Sort of like iDoser?

Is this for real? Or is it some sort of a joke?

I wanted to try it out but could never get it to work. It just sorta hangs there at the setup.
