WOPR (War Operation Plan Response)
From the movie WarGames.
During the movie a small display on the WOPR computer indicates a war game simulation is running and
there is no actual attack. The display indicated 'GAME TIME ELAPSED' as the simulation continued.
Friday 05 November 2021 I didn't feel like going out after work and knocked up a quick simulation of that
display for a bit of fun. 'Game time' is 17:00 Friday until 08:00 Monday, the remainder 'Work time'.
