Can’t believe we missed this. Flashing LED Internet telepathy. Nice.

In James’s experiment, two people are hooked up to EEG amplifiers that measure activity in specific parts of the brain. The first person generates a series of zeros and ones, imagining moving his left are for zero and his right arm for one. The first subject’s PC recognizes those thoughts as ones and zeros and transmits them over the Web to the second subject’s PC, which flashes an LED at two different frequencies for one and zero. The EEG extracts the LED light’s information from the subject’s visual cortex and parses it back into binary code. Thus, brain-to-brain communication is achieved.
