Building a Procedural Hex Map with Wave Function Collapse
I've been obsessed with procedural maps since I was a kid rolling dice on the random dungeon tables in the AD&D Dungeon Master's Guide. There was something magical about it — you didn't design the dungeon, you discovered it, one room at a time, and the dice decided whether you got a treasure chamber or a dead end full…

Chess engines do weird stuff
Since AlphaZero, lc0-style chess engines have been trained with RL. Specifically, you have the engine (search + model) play itself a bunch of times, and train the model to predict the outcome of the game.

My 1981 adventure game is now a multimedia extravaganza
Over the last few weeks, I created a computer game set in the Arctic. Or maybe I’ve been working on it since 1981. It all depends on how you count.

A Pokémon of a Different Color
Do you notice a difference? The image on the right appears “yellower” than the image on the left, which looks more goldenrod by comparison.

Building a 24-bit arcade CRT display adapter from scratch
In November, my friend and fellow Recurser, Frank , picked up an arcade machine for the Recurse Center . We call it the RCade. He wanted to leave the original CRT in - which I think is a great choice! - and drove it off of a Raspberry Pi. Eventually we wanted to move to a more powerful computer, but we needed a way to…

Nintendo DS code editor and scriptable game engine
I built a scriptable 3D game engine for the Nintendo DS so you can write and run games directly on the console itself. Written in C using libnds , it compiles to a 100KB .nds ROM that runs at 60 FPS . Features a touch-based code editor on the bottom screen and real-time 3D rendering on the top screen. Ships with a…

Video Games as Art
Video games are art, but a strange art: their essence is transformation of the player, not description to the player. This makes meaningful criticism nearly impossible—you can point at the moon, but it’s not the moon, and once someone sees it, they no longer need the pointing.

Implementing a tiny CPU rasterizer (2024)
In the OpenGL course I'm teaching at a university, my students learn that the GPU uses something called rasterization to draw stuff on the screen. Then, I explain how — in theory — rasterization works, e.g. how would one write the code to draw a fixed triangle on screen. Of course, the GPU does that for us, but it is…

Snow Simulation Toy
One of the first significant things I ever coded in QBasic was a falling snow simulation- I think they're very soothing to watch, fun to customize, and there's lots of possibilities for extra little delight. Here's one I built on idle afternoons over the holidays this year at my parents. Enjoy!
