Computer Space, generally considered the first commercially-sold video game ever, is pretty rare these days, with only about 1800 of the retro-futuristic arcade cabinets made. Yet two of them just popped up on eBay.
Created by Atari founders and all-around gaming legends Nolan Bushnell and Ted Dabney, Computer Space came out in November of 1971, a full year before Pong hit the streets. The gameplay seems like sort of a mix of Asteroids and Space Invaders, with a rotational thruster (that phrase will never cease to sound filthy) controlling a rocketship (it's just getting dirtier) trying to take down a UFO (well, if a UFO is a euphamism, I don't want to know what it's referring to).
There's a green and a yellow version for sale, and the price is currently hovering around $1500 and $2500, respectively, but it's kind of an awesome-looking piece of furniture even if you're not into classic gaming. If you like those uncomfortable egg-chairs, this'll fit right in with your aesthetic. [Technabob]
