10-36-55.pdf user-mode programs: pool game
This game, written by ken, used the Graphic 2. One of its
earliest tests--random starting positions and velocities on
a frictionless table with no collision detection--produced
a mesmerizing result. This was saved in a program called
"weird1", which was carried across to the PDP11.
Weird1 was a spectacular accidental demonstration of structure
in pseudo-random numbers. After several minutes the dots
representing pool balls would evanescently form short local
alignments. Thereafter from time to time ever-larger alignments
would materialize. Finally in a grand climax all the balls
converged to a single point.
It was stunning to watch perfect order emerge from apparent
chaos. One of my fondest hopes is to see weird1 revived.
