How It Works
Squareeater uses a combination of binaural beats and psychostrobic flicker effects to attempt to induce brainwave entrainment in the viewer.
Binaural beats are achieved by putting a tone in one ear of the listener and a slightly different tone in the other. For example, if the left ear is hearing a sine wave tone of 397hz (cycles per second) and the right is hearing 403hz, the brain perceives a pulse of 6hz, the difference in the frequencies.
Under ideal conditions, frequency following response occurs in brainwave functions, meaning the brain starts to function at the same frequency as the binaural stimulus. Different frequencies of stimulus correspond to different brainwave states, for example 4-7hz correspond to theta waves, a brain state associated with deep meditation or early stages of sleep.

lol, thanks for the props!
We know folks are suspicious, so tried to put some good info up here:

I'm really not surprised it has an effect. After finding some glasses that had a breath controlled fan in front of your eyes to induce a strobe effect, I built some glasses that flashed lights with a control dial on the side. The result can be compared to driving a car along a road in the afternoon with the sun shining low through the trees (which also makes me feel a little ill). The addition of the audio only heightened the effect for me. Very interesting stuff!
