Using a Muse EEG headband (which I just happen to have) you can move your head up and down or side to side to scroll vertically and horizontally through Netflix's interface. Then, when you've landed on a title you like, just think of the word or action "Play."
No word on if they'd ever roll this out publicly as it was part of their annual Hack Day. Also… I don't know that many of their users have a Muse headband (which is primarily used for meditating) so there might not be much incentive to do so. Still… I would love to try it. Hit me upif you want a dummy tester!
