Doom on PC. Doom on Windows. Doom on Mac. Doom on Unix. Doom on the
SNES. Doom on the Saturn. Doom on PS1. Doom on Java-phones. Doom on
Sansa ClipZip. Doom on Zune. Doom on network routers. Doom on a
smart-fridge. Doom on digital camera. Doom on a cash register. Doom
runs on everything.

But there's always been one platform nobody ever asked, "Can Doom run
on this?" And that was Doom itself. Can Doom run... on Doom?

Yup.
https://www.youtube.com/watch?v=c6hnQ1RKhbo

Thanks to a code-execution exploit, it's now actually possible to
launch Doom... in Doom itself. This isn't a specially modified version
of Doom (well, other than a WAD that overwrites key variable to launch
an external program); the core executable code is untouched. You can
just watch the demos play out, or switch to the embedded version and
play it full-screen. It really is Doom inside of Doom.

Sadly, the video doesn't answer if Doom can play inside of Doom inside
of Doom. How deep down the rabbit hole can we go?!?

They need to go more! :)

If you have to ask, you don't want to know.

You forgot running on a pregnancy test:

So yes, really anywhere!

Oh, I wasn't trying to make a complete list.
(there's a website for that anyway: https://itrunsdoom.tumblr.com/ )

It also runs on printers, and Peletons, and karaoke machines, and cars
.... and... and... and...

At this point its probably easier to list digital computing devices it
DOESN'T run on.

But this project makes me think, "what we really need now is a Doom
OS".

Which isn't really as far-fetched as it sounds. DOS games were often
operating systems unto themselves, doing their own memory management,
hardware drivers, file management, etc (it's one of the main reasons
Windows95 took off the way it did; its hardware abstraction layer
meant developers no longer had to worry about that sort of stuff). But
add some extra disk-management and bootloader code - and a more robust
way of launching external programs - and Doom could be an OS unto
itself.

The inevitable bugs would be terrifying, however.

Yes of course their's a website for that. Should have guessed. :D

It's not quite what I had in mind but:

DoomOS
https://www.youtube.com/watch?v=uxnnMzRWb8E&t=7s

(this one reminds me a lot of the IRIX 3D filesystem manager
popularized in Jurassic Park)

There's also PSDooM
http://psdoom.sourceforge.net/screenshots.html

(although, again, not quite what I had in mind. I visuallized using
Doom as the underlying code and maybe utilizing some of its motifs,
but not one that actually required you to traipse around literally
killing processes or files. But these are fun nonetheless)

Anyway....

We need a "rule 34" for Doom. I recommend:

Rule 66: "If there's a digital computing system, somebody will
eventually manage to get DooM running on it."

.... or perhaps:

Rule 93 (in honor of its release year): "A digital computer is not
considered feature complete /until/ DooM is running on it."

Although, if the latter is true, how long before DooM is embedded into
a CPU's circuitry? ;-)

Unless it was a different one, tt's not actually Doom running on a
pregancy test. It's Doom running on a custom computer stuck inside the
shell of a pregancy test.

The actual pregancy test didn't have a dot matrix display and could only
display simple symbols showing the result of the test, so couldn't run
Doom even if it's CPU were otherwise capable.
