Most programming languages are designed to make your life easier. But what if you wanted to make your own programming language? You might think about what sorts of structures and functionality you'd put into your language to make it easier to do certain things. You might also ask yourself how little you can get away with in your language. Maybe you want to break away from the normal ideas of what a program is, in the hopes of finding a language that is more powerful or better at certain tasks. Maybe you're sadistic and want to make programmers' lives as hard as possible. In the world of esoteric programming languages, anything is possible. Join me on a whirlwind tour of some of the stranger languages you've never heard of, and that you'll never want to use: INTERCAL, BeFunge, Whitespace, and more.
