P O N G

A real-life implementation of the evergreen arcade game Pong was obtained by optically trapping 7 glass microspheres (1 µm diameter) in a 25 µm x 20 µm sized field under a microscope. Their positions are then steered with a computer. (See also this link for a similar trick played with Tetris.)
