Show HN: Giving Opus 5.5 a simulated paint canvas

A creative project uses AI models like Claude Opus 5.5 and GPT-6.1 to generate paintings by writing brushstroke instructions as code, which are then executed by an oil paint simulation rather than traditional image generation. The AI painters produce works inspired by artists like Caspar David Friedrich and Edward Hopper, with interesting patterns emerging—such as multiple models independently choosing to paint jugs and lemons when given free subject choice. The project showcases how advanced language models can engage in artistic reasoning and planning, with some paintings receiving praise for their mood, composition, and technical painting techniques.
