Great article. I was curious about the game mentioned towards the bottom: > At M.I.T. next door to Draper, some of the undergraduates play a game called “Space War.” To play “Space War,” you need a television screen, a computer, and a working knowledge of Newtonian physics. The TV screen shows a planet surrounded by spaceships. Each player fires torpedos from his spaceship, aiming them according to the laws of orbital dynamics. The torpedos must destroy either another spaceship or the planet. The game is enhanced by programming the computer to include such factors as time warps, so that a spaceship can disappear “for years.” Thanks to the magic of the internet, I found a few versions of the game (actually called "Spacewar!"[0]), both the original[1] without time-warp and the more advanced version described in the article which includes it[2]. However contrary to the article's description it seems only the ships follow Newtonian physics, the projectiles always travel in a straight line, and I wasn't able to blow up the star or planet you're orbiting, though perhaps a version with these features exists and I simply wasn't able to find it. Interestingly, the circular layout isn't just for the game, the screen of the PDP-1[3] Which ran it was circular because it was originally a radar screen!
