For better or worse, the 1993 demon-blasting video game Doom is one of the most influential games ever. Which means we get amazing fan tributes like this: a piano rigged to act like a keyboard for the game.

A team of game developers got together and wired keys in the piano to a PC running the game. When players hit certain notes, it’s the equivalent of hitting certain keyboard commands. Each white key corresponds to an action, like moving, while each black key fires. (C-sharp to shoot frantically at the hell-beasts.) A screen in the front of the piano shows the action.
