Build a live wallpaper that follows real meteor shower dates

Tired of the same looping wallpaper video, the poster (u/Ilovcyclynn on r/codex) built a lighthouse scene that changes with the calendar. They generated one still background with Seedream and a six second clip with Seedance through an Atlas Cloud API key. Codex wrote the rest: the JavaScript and WebGL animation, a table of the 2026 meteor showers, sunset and twilight times for New York, and a scheduler that raises meteor density around the November 17 Leonid peak. Each meteor gets its own position, speed and lifetime. The demo has sliders for date and time so the poster can preview how the scene changes.

The wallpaper runs as described in the posted video. One thing looked wrong at first: reflections on the water did not match the meteors overhead. They were changed to track each meteor's path and fade, with a slight ripple. Outside a shower window or in daylight the animation and video stop and the still scene stays. The poster puts the image and video cost at roughly $0.58 at listed rates and gives no figure for the Codex time.

Commenters asked how hard it loads the GPU and whether the sunset maths survives the daylight saving switch in early November; the thread shows no answer to either. The calendar and location are hard coded for 2026 and New York, so anyone reusing the idea needs to swap those in.
