Interesting.... I don't know about the rest of you, but I'd be willing to sign up as a guinea pig... If it's for real.
I don't know if this is such a good idea for technology to get into manipulating physiology, though... I like my fluids just fine. However, the medical applications could be revolutionary. Like a cortical stimulator from Star Trek or something...
However, when it comes to the gaming application, it'd be unnecessarily expensive... The actual device itself being super tech and all, not to mention the programming and technology needed to implement such a device.
As to whoever said "why is she smiling the whole time?," I have to ask how often you experience new sensations. Supposing it works, I don't see how the experience would be any different from getting drunk the first time: you loose control of mobility, sometimes even stumble over yourself, and your brain feels like it's wooshing around in your skull.... the over all effect is very strange yet "tingley," and it's so fascinating that you just find yourself grinning unctrollabley... The "wooshing brain" experience is probably what she's going through.
