Doom is an all-time classic. Back in 1995, it was installed on more PCs the Windows 95, and now it's found its way onto almost every gaming platform out there. The most recent console Doom Guy now also calls home is the Nintendo Switch, but the FPS hasn't just found its way onto various conventional platforms. Thanks to homebrew fans, hackers, and programmers, Doom is running on all kinds of machines. If it has a screen, you can probably see Doom on it. So without further ado, let’s take a look at some of the strangest, shall we?

A pregnancy test

Yesterday I had a lot of retweets and reddit posts and such for playing Doom on a pregnancy test.But as I explained then, it wasn't really PLAYING on a pregnancy test, it was just a video being played back, not an interactive game.Well, now it is.

Yes, Doom is now playable on a pregnancy test. With its monochrome pixel 128 x 32 display, it's a teeny tiny way to get stuck into the classic FPS. Programmer Foone replaced the existing CPU and swapped out the LED display for OLED since a pregnancy test couldn't run the game as is. Controlled using a keyboard, Pregnancy Test Doom is certainly one of the more unusual ways to take on the role of Doom Guy.

An Apple watch

Simultaneously as impressive as it is impractical. This is what happens when tech people have a hackathon. On the one hand it’s amazing that what was the peak of gaming in 1995 now runs on *a watch* but on the other, it’s not entirely a practical way to play the game.

A portable plate edge bevelling machine

This is a little like cheating because it is just a big computer, albeit one that adds PVC strips to furniture on an industrial scale. Still, let’s not underestimate the skill involved in making Doom run on a something more used to applying the finishing touches to showers and kitchen cupboards.

A Macbook touch bar

Probably the least practical Doom hack ever, creating a version of the game that appears to be in a 100:10 aspect ratio. Kudos for getting it to work, but it looks like a visual representation of a migraine and probably plays like one too.

A printer

What’s interesting here is that this famous Doom hack was actually part of an experiment to show security exploits in wireless printers. It was, at one point, possible to force a firmware update on a printer and make it run any software - spying stuff for example to sneak a look at what was being printed. Or, in this case, a version of Doom.

A graphics calculator

Graphics calculators are good at one thing mainly: graphical calculation. In terms of innards they don’t have half the things you’re supposed to need to do this, like loads of RAM or a GPU, which makes a working version of Doom here more witchcraft than anything else. Apparently it drains the batteries in minutes.

On a single key

The Optimus Maximus was a $1500 keyboard that had a programmable screen on every single key. The idea was you could map just about any lettering or symbols to it depending on the game you were playing. And, if we’ve learned anything so far, is that anything with a screen will be forced to run Doom. In this case in a glorious 48x48 resolution.

Public access tablets

I’m not sure this is what New York had in mind when it provided hundreds of public kiosks to give people free computer access and WiFi. Still, if it can run Doom, it should. This isn’t a true hack, though, as it’s really just playing an online emulator via a browser, but it counts all the same.

This old Sony phone

It might not play any sound but this old Sony K-800i apparently “runs okay.” It’s made possible by patching the firmware to let the phone run custom executable files. Like Doom. Because what else are you going to do with phone from 2006, call someone?

On a camera

What’s most impressive about this is that the 1998 Kodak DC260 digital camera is almost as old as Doom itself. A lot of things on this list work because time moves on and there’s now enough power in a watch to run a game that originally needed an entire PC. Bonus points for the fact that this has a TV out as well if you want a bigger screen.

On an old iPod

Not just an old iPod, but a Nano at that, for extra showing off. This is probably a hack you could do yourself if you had one lying around, as there’s an Instructables guide detailing the steps needed to do it.

An ATM

Not having any of the right buttons has certainly never stopped anyone running Doom on a thing. So an ATM? Sure, whatever. As well as getting the game working on a cash machine, these ambitious hackers have also got it using the buttons on the side of the screens, swapping the $10, $20 money options for pistol, shotgun and so on.

Doom

There are so many different versions of Doom now that almost anything is possible, including GZDoom, an open source port that includes support for arcade machines capable of playing other games. Like Doom. In Doom. Doom squared, if you like. Yes it is a bit Inception-y.
