Video game
BJ Best

Does a video game need a player? HSSBSB argues no, being the first zero-player game for the Atari 2600. It is experienced by watching a square randomly traverse an endless map of mostly empty screens. Occasionally, an abstract item appears on the screen, and the square might collide with it, earning points. And so the game continues, the score creeping ever higher. The game runs on a cartridge and original hardware.
