'Brain control' Emotiv headset
 

Though their press conference on Tuesday night was ... well, it was a disaster (watch our video to relive every cringe-inducing moment), that didn't stop the electroencephalographers at Emotiv from demoing their technology on the GDC show floor to, evidently, better effect. Mahalo Daily's Veronica Belmont donned the cephalopodic contraption and, using nothing more than the power of her mind, managed to make a box disappear. While the technology appears to work well enough (now), we're still not sold on it as a real gaming interface and not a novelty.
