Weirdest Things People Have Made Doom Run On

A Canon DSLR became Gamescom's newest Doom machine, using the camera's own buttons to control a game the hardware was never designed to display.

The pregnancy test's original display was replaced, but the tiny plastic device genuinely processed Doom, preserving the stunt's essential absurdity.

An ATM has enough conventional computing hardware to run the game, although playing Doom on a machine designed to dispense cash remains beautifully unnecessary.

An Apple Watch offers almost no useful screen or controls, but apparently a wrist contains enough hardware for a recognizable trip to Mars.

The MacBook Pro Touch Bar produces the world's widest and shortest view of the first level, technically playable and practically ridiculous.

Running Doom on a digital camera postpones photography until the Cyberdemon is gone and turns familiar control buttons into an improvised gamepad.

The printer's display refreshes terribly, which turns familiar demons into flickering threats and somehow makes the old shooter look more menacing.

Graphing calculators became the school-computer classic for Doom ports because determined students found enough processing power behind those tiny monochrome screens.

A John Deere tractor display can open the gates of hell between field operations, proving agricultural hardware is now far more capable than necessary.

An oscilloscope reduces Doom to glowing green vector-like lines, yet the corridors and enemies remain immediately readable as the same game.
