vertumnus is a tool to create customized printable posters of what's in season at local farmers' markets. It lives at vertumnus.fyi, at least, as long as the domain name and Github Pages remain affordable.
I've written a whole page about it. But the short version is: I wanted to do a silly side project, and I mistakenly thought that dry farmed early girl tomatoes were in season way earlier than I thought they actually were, so why not spend a disproportionate amount of time making a poster to tell me that?
The poster itself is React SVG elements written with d3, with the watercolor pictures (plates in the codebase) doing some simple gap finding heuristic for placement. Data is pre generated via a set of scripts.
From a clean git clone, it should be as simple as bun install + bun run dev.
