Thought Control

Here's a topic that has got me thinking.  A company (or person??) has quietly announced Puzzlebox Brainstorms.  They claim to have available hardware and software that can pick up your brain activity using an EEG headset and use that to control a NXT robot.  I am a little skeptical; the video doesn't show much but a computer monitor with a remote controlled NXT robot.  I believe it can be done, but the website doesn't give much information either.
