A strange little side quest
There is a neat bit of history hiding behind the kind of play you find in De-animator. Gun Fight reached arcades in 1975 and became the first arcade video game to use a microprocessor. The same trail leads to another fact: In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. Not bad for a few facts hiding behind a Play button.
