Sonnet 5.5 builds a 1,500-leaf autumn simulator in one HTML file
The author asked Sonnet 5.5 to build a paper-cutout autumn foliage animation with 1,500 falling leaves in a single HTML file; it ran on the first try at 60fps on iPhone.
I gave Sonnet 5.5 a hard one: build an autumn foliage simulator in a single HTML file. Layered paper-cutout look. Big tree, rolling hills, grass. Rough-edged paper, grain, soft shadows. 1,500+ leaves that flutter down (not straight down) and pile up. Drag a finger to make a gust that blows falling and settled leaves and shakes the branches. Wind slider. Regrow button. 60 fps on iPhone. The result: a 23 KB file that ran on the first try. The leaves did everything I asked. It looks stellar. Totally nailed it. Setup: I ran it through the Nous Research portal, with my Hermes agent as the orchestrator. Full prompt and in the first comment.
