Hello, world (again)

Every few years I rebuild my personal site, and every time I face the same question: what is a personal site even for anymore? Everything factual about me is one search away. The site's real job is to show how I think about building things.

So this time there are two front doors. The main one is a 2D platformer — you run right through a day that turns to night, bump ? blocks, and my bio, projects, books, and patents pop out of them. It's the most honest résumé I've ever made: I learned to program because of games, and I still believe software should be fun to touch.

This page is the other door — for people who just want the facts, and for me to have somewhere quiet to write. If that's you, welcome. The coins are optional.
