Regressive JPEGs

https://maurycyz.com/projects/bad_jpeg/cats.jpg
The post explains how JPEG progressive scans can be used to progressively display low‑frequency data, and how the author exploits this by concatenating multiple scans (mostly DC‑only) to create a pseudo‑animation that works in browsers up to about 90 frames. Although this trick bypasses the usual 9‑scan limit and avoids ghosting, it has no real practical use because timing must rely on ...

I'm Making Strandfall, a Solarpunk Orienteering Larp

https://mssv.net/wp-content/uploads/2026/04/assembled-no-case.webp?w=1024
In the twenty years I’ve been making games, I keep returning to the idea of blending the digital and physical worlds through ARGs like Perplex City and location-based games like Zombies, Run! It’s as if the act of mixing worlds enchants them both. That impulse is probably why I recently became fascinated by Nordic Larp (live action role playing), the closest thing we have to a fully embodied, ...
