The author seems to have done it, at least in part, for the purposes of iOS development. That seems to be a bit more compelling than "because you can", though Doom running on refrigerators and pregnancy tests shows that's already plenty on its own.

If that's a real example and you didn't make it up, I want to know what pregnancy-test devices have enough buttons to make it possible to control the game. Or are they coming with touchscreens now? Refrigerators, sure, I can easily see that. But pregnancy-test devices? Why would they have enough buttons to be able to simulate WASD and a fire button? The only pregnancy-test devices I've seen are the home test ones where you put the sample in the device then wait to see if there's one line or two (some of them arrange the two lines in a + shape so that - means a negative result and + means a positive result, which is clever), with no electronics. What pregnancy-test devices are using more than that?
