It may look like something that'd be at home in iTunes, but this visualizer developed by NYU student Phan V is linked to something even more unique to you than your music collection. With the aid of a mic'd up stethoscope, it's able to visualize a person's heartbeat in a manner that has quite a bit more punch than the usual means -- the person's pulse rate determines the speed of the animation, while the volume of the heartbeat captured determines the brightness. Practical? Maybe not, but you can check it out in action in the video after the break.
