This was recently demoed at TED [1], and I was impressed how much this field is being commercialized. $US500 for a headset and SDK, shipped worldwide. I admit ever since I was a little geek, I dreamed one day I would have neural access to a computer, and now it looks like it's coming along far enough to play with. I was wondering what the community might think.
