217 lines of pure SQL render a pelican on a bike via SDF raymarching, no SVG or bitmaps
fofrAI · x · 2026-10-24
fofrAI shows Gemini 4 'Argon' writing 217 lines of pure SQL that render a pelican riding a bike — no SVGs, no bitmaps, no extensions.
The gist implements a per-pixel signed distance field (SDF) raymarching shader inside in-memory SQLite, outputting a raw 800x800 Netpbm P3 PPM image, reproducible with a single sqlite3 :memory: < pelican.sql command.
