Quick Study
Claude Opus 5.5 High generated a canvas-based photo painting tool in a single prompt
“Build an artifact where you open a photo and it rapidly (in a few seconds) paints a version of that photo using a canvas element and simulated paintbrush”
Simon Willison used a single prompt to Claude Opus 5.5 High to generate a working browser tool that simulates oil painting from photos using canvas and Sobel edge detection. The tool requires no external libraries beyond Google Fonts, demonstrating Claude's ability to produce non-trivial creative coding artifacts from minimal prompting. This is a casual demo rather than a major announcement, but illustrates continued capability growth in code generation for visual/creative tasks.
