A strange little side quest
The fun part of looking behind Blob Opera is seeing how many older ideas are still alive in modern play. In 1958, Tennis for Two used an analog computer and an oscilloscope to turn simple physics into a playable tennis-like demonstration. It also connects to a different milestone: Computer Space reached arcades in 1971 and became one of the earliest commercial electronic arcade games, even though its controls proved demanding for many players. That history is one reason familiar mechanics can still feel new when they are recombined well.
