Painting with Claude Fable 5.2: each artwork is a 1000-line Python brush engine

Responding to criticism that Opus 5.5's paintings merely imitated real art, jkeatn used Claude Fable 5.2 to invent fictional artist personas with consistent, datable styles. Workflow: the author steers with comments while Claude revises the code powering brushes and paint engines. Each piece is a 1,000-2,000 line Python program placing every stroke through a simulated paint engine with different bristles — thousands of strokes per painting, sometimes pushed much higher. Results (waterslide, ice-rink dragon, braided river) look nothing like real art movements.
