If the theremin wasn’t impressive enough by allowing you to control the music by waving your hands around, this latest mod takes it one step further, allowing you to control the music with just your mind (who needs hands anyways). A Mattel Mindflex game was modded into a controller interface for this instrument, allowing the user to control the pitch just by thinking. The more you think, the higher the pitch; the less you think, the lower the pitch. You can check out a video of it in action after the jump. Doesn’t seem like you’ll be the coolest DJ at the clubs with this, but it’s still quite cool to watch.
