Until a recent episode of 99% Invisible, I had no idea that You Are Listening To had a numbers station child site. But it does. And it’s pretty amazing.
I’ll go ahead and spare you from my amateur synopsis of numbers stations. Instead, load up You are listening to Numbers Stations in a new tab and spend a little quality time with the Wikipedia page in another one. Once you’ve worked through that, there’s also the resources over at The Conet Project.
Sorry in advance if this manages to make you into a crazy person.
