Anyone who has every tried to learn the drums can tell you humans are capable of true multitasking. Limb independence seems like an impossible feat when you first start out.
I don't know if it's still there, but the Science Center at the Reuben H. Fleet Space Theater and Science Center in San Diego used to have a device that was a good demonstrator of this. It had four double rows of lights, with two foot pedals and two twist handles, and a counter. It would randomly light one bulb in each of the paired rows, and by manipulating the pedals and handles, you could move the lit bulb in the other of each paired row; when you got all four matching, a counter would increment and the lit bulbs would be randomized; the goal was to get as many matches as possible before the timer ran out. Watching other people do it, I would regularly see results in the 8-15 range, with people laboriously matching one light, then the next, then the third, then the fourth, which seemed so inefficient, so I worked at it, not focusing my attention on any given light while I moved all four controls to an approximation of the correct matches before making fine adjustments for a match. After a bit of practice, I could get results consistently around 35-45 matches, and I'd usually wind up with a bunch of people watching me.
