This is Christopher Hills. He's an Apple fan. He also has cerebral palsy, and as you'll see in the first video below, he can't control his muscles easily. The incredible thing about Christopher, though, is despite that, he edited these three videos himself. Not unlike Stephen Hawking, he uses a single button to manipulate his computer, which he presses with his head, connected to a device called a Discover Switch. He also has enough patience and optimism to touch the hearts of thousands of YouTube viewers.
