Subconscious computing

I recently volunteered for an experiment in brain-computer interfaces, here at MSR. It involved having a multitude of electrodes clipped to my head and the brain signals were being collected. Folks at UW are doing some cool stuff on this front. Check out

Imagine being able to control machines with your brain. Powerful. Just imagine the other way round, scary!
Meanwhile, I'm hoping they cant figure out what I was thinking using those brain signals!
