26 games written in the Odin programming language, one for each letter of the alphabet.
I remember hearing a story about how John Romero of id Software fame had learned to program games better by making one a week for some period of time. I've been wanting to learn game programming myself and thought this might be a good way of doing so. And thus Odin 26 was born. I'm not timeboxing each game (because I have other work/life obligations), but in general, a week is the goal (though it seems that it generally does take a bit longer).
