Claude Drawing
Use Python (only depends on numpy + Pillow, runs with the system's built-in python3) to "draw" images by following the physical rules of brush, ink, pigment, and paper — without calling any generative model.
- Controllable composition: Every stroke is computed; the layout, white space, and accent color positions are precisely controllable.
- Reproducible results: With a fixed random seed, the same image is produced every time.
- Animation-ready: You can output stage snapshots to create an animation of the painting being built step by step; generative models can only produce a single full image.
