3000 lines of JS with Claude Sonnet 5.5: a fully procedural WebGL forest

measure_plan · x · 2026-09-29

Developer measureplan shared experiments built with Claude Sonnet 5.5 over the past week. The standout: a "forest made of JavaScript" — roughly 3000 lines of JS and WebGL shaders procedurally recreating the feeling of sitting under a leafy canopy, with everything (including sound effects) rendered in realtime and no external assets or 3D models. An early hands-on test of the new model's creative coding chops.
