A generative canvas redrawn from weather, tide, swell, and sky data sampled at 24
points across San Diego County, 13 layers deep, with 30 days of sediment building up
behind it. Begun 7 September 2026 — still running.
Data comes from Open-Meteo (weather, swell, sea temperature), NOAA Scripps Pier
(tide), and computed sun and moon positions — nothing about the piece is
pre-rendered; it re-fetches and redraws itself on a 10-minute interval, live right
now, a few miles from where it hangs.
- 2026-09-11 Sun and Moon are now live orbs on their own real rise/noon/set (Sun) and rise/transit/set (Moon, found numerically — it has no closed form) arcs, sized to scale with the canvas. Replaced the old fixed "first light" marker; the wall's caption now leads with the day count and time, followed by a Solar/Lunar almanac.
- 2026-09-11 Fixed an intermittent bug where the wall's live-reading footnote could get stuck on its placeholder text forever, with no error — its update listener could attach to a throwaway document the browser creates before the artwork's iframe finishes navigating in. Also removed the dark-mode canvas spotlight glow.
- 2026-09-08 The How It's Built sample-grid map moved from its own section, into the layer picker, then onto the canvas itself as a direct overlay, with an Off/Grid/Land & water/Topo toggle.
- 2026-09-08 Layer picker, layer descriptions, and a live sample-grid map added at /how-its-built.
- 2026-09-08 Wall lighting switched from automatic sun-tracking to an explicit Light/Dark/System toggle.
- 2026-09-07 First version live — 24-point wind grid, tide, swell, and sea-temperature color all sampled from real data.
