Generative art driven by live stock market data. At the open, midday, and close of each trading day, market and volatility moods become a river landscape through versioned templates, not ad-hoc prompts. Every image traces back to the market snapshot that made it. One visual style, systematically varied.

On the live page, weather in each image is selected for the viewer's location, and up to nine recent snapshots are shown across market days.
