keyviz
I built a little overlay that shows my keypresses for screen recordings
An always-on-top window that fades in the keys I press, for demo videos. One afternoon in Tauri. Makes my recordings way easier to follow.

Draw a shape and Plink turns it into an evolving little melody with a tiny synth in the Web Audio API. No samples, all synthesis. Weirdly meditative, I lose ten minutes to it daily.
A weekend WebGL toy: 200k particles that flock and scatter around the pointer. Pure shader math, no physics library. Mostly an excuse to learn compute-ish tricks in WebGL2.
WebGL plus an entity component system in 8kb, with a level editor that runs in the browser. My kid and I built three little games with it over a holiday.
