In 2001, Animusic released the groundbreaking all-CGI music video "Pipe Dream," featuring a variety of instruments being played by bouncing metal balls.

Ten years later, Intel and Sisu Devices released their own real-life version, performed by a seven-computer rig at the Intel Developer Forum.

Although they may have cheated a little bit by using synthesizers instead of physical instruments, you've got to admit this project took balls to pull off.
