Simon Willison prompts Claude Opus 5.5 to build a photo-painting artifact
What happened
On 24 October 2026, Simon Willison reported that he gave Claude Opus 5.5 High a prompt asking it to build an artifact that, once a photo is opened, draws a version of that photo within seconds using a canvas element and a simulated brush. The report notes that he had previously had Claude Fable simulate a watercolour illustration effect with P5.js. Progress so far stays at the level of building the artifact and describing its effect; the report does not mention further testing or a release.
