Before Wiis and PlayStations, before you boasted about how many bits your console had, and before Ralph Baer's Odyssey first hit Sears shelves, a bored physicist at the Brookhaven National Laboratory cobbled together a little digital diversion called Tennis for Two. Those early days of gaming were spent lobbing a lurid green ball back and forth across a tiny oscilloscope screen, so it's only appropriate that you can now tear through Quake's corridors on a similarly screwy screen. Finnish programmer/artist Pekka Väänänen runs through the process of converting an intensely visual game into a series of sounds that an aging Hitachi oscilloscope interprets as the building blocks of a world here. The end result? Well, it's nothing short of mesmerizing, a simultaneously foreign and familiar take on an experience most of us have long since committed to memory. Don't just take our word for it, though: There's video evidence waiting for you after the jump.
