I had a coworker who got to try it out at the GDC and she said it is pretty rad. One of the games it has is where you're this anime guy and you have to pick up objects by thinking about them. What she didn't realize was that the sky would change colors depending on how hard you were concentrating so she saw she wasn't trying really hard then thought full force at it and all the rocks went flying and the sky became multiple colors.

Just from that description it sounds awesom.
