A strange little side quest
If Dark Idle sends you down a curiosity rabbit hole, start here. In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. That is only half the story. Nintendo's Donkey Kong arrived in 1981 and introduced the character first known as Jumpman, who later became Mario. The screen is modern; the urge to test skill, pattern and timing definitely is not.
