How I reuse old monitors, and not for my PC

If you've been using PCs for at least 10 years, chances are you have an old monitor stashed somewhere in your house (if you haven't gotten rid of it, that is). It might be your older 27" 144Hz gaming monitor, an even older 24" 60Hz display, or an ancient 15" CRT monitor — whatever it is, you can find fun ways to reuse it. And I won't be reminding you to use it as a secondary monitor for your current PC, or anything similar. I'm also not going to rehash the ideas shared in the article linked below by my colleague Joe Rice-Jones. So, let's get into it.
