Some of you may know what it is, but I'll give a brief explanation anyway.
Brain wave stimulation is a way to entrain the EEG frequencies of the brain, thus producing the desired state of awareness: Alert, Relaxed, drowsy, and asleep. This is usually done via auditory stimulation. Different combinations of the above states make better atmospheres for learning, or taking tests.
Sounds spooky, huh?
Well I'd like to know what Everyone thinks of this, as I have been using it to help me sleep, and it seems to be working. Below is a link to one of many websites on it... This one gives a more thorough explanation and describes the effects more vividly.

There is also a place on this site to download a tone generator that is supposed to produce the brain-altering tones, it is the one which I have been using with good results, here is the direct link:
