Had no idea I'm involved in that one too, but hey, since I'm thinking, I must be, right? I briefly looked over the first two articles and I think you're on to something. I used a very interesting device, sold for $99, called MindWave (http://neurosky.com). I even started to code an app on iOS, but at that time, 3 years ago, the tech wasn't very advanced. I saw they now a new headset now, for about $199. It may be worth exploring. Oh, by the way, I never take less than 10% for my involvement in a currency project. Just so you know :)
