Other than "amazing," you may also call the above contraption DeepNote. It's a working robot that can totally destroy you in Guitar Hero. Using a pair of "eyes," it watches the action on-screen, then playing those very notes in real-time. It's all done via a series of photodiodes, which pick up the changes in light from the screen in up to eight nanoseconds. As evidenced by the video above, this thing actually works and is quite impressive.
