01 — The panel
A cinema the size of a postcard.
A 32×64 RGB matrix. Adafruit HAT. Isolated CPU core for the refresh thread. Uncapped frame rate so rainfall, pong, and stick fights never pulse.
It lives on a Raspberry Pi Zero 2 W, in Docker, on the LAN. You configure it from a browser. The panel never goes black — failed fetches keep the last good frame.
02 — The feed
Three kinds of page. One rotation.
Yahoo Finance
Equities, gold, indices. Ticker color follows the US session: open, pre, after, closed.
FinD
Whole units. Today’s change. A 64-column sparkline from the machine on your LAN.
03 — The stage
The chart is a stage.
Pages slide, fall, or get wrecked. Fireworks freeze the current frame. Two stick figures fight on the sparkline. Two paddles rally until the glyphs explode.
Press a cue. The preview plays it. On the real panel it lasts eight to ten seconds, then the page redraws — destruction is overlay-only.
04 — The room
A control room, not a form.
The web UI is a 64×32 preview, a rotation you can drag, an inspector for every field, brightness that dims the canvas live, FinD under the stage, and a Pi strip that can restart either container. Save only when something changed. The old tabs still exist — archived, not advertised.
05 — The rig
Small computer. Loud pixels.
