Forget gaming PCs. Forget Doom on an ATM. Forget Super Smash Bros. on a graphing calculator. The only game worth playing is Quake on an oscilloscope. I mean, holy crap would you look at this thing? It's as nerdy as it is awesome.
Oscilloscopes are typically used to track the variance of an electrical signal. It's a simple job that mostly involves a lot of wavy lines. They're good for games too though; An oscilloscope gave rise to Pong's great-grandfather, but this version of Quake is on a whole other level. Creator Pekka Väänänen explains the hack in great detail on his blog but really the video speaks for itself.
