Procedurally Drawn Running Red Fox Animation

A procedurally drawn red fox run cycle in HTML5 Canvas 2D, about 13 seconds long. The vector-style fox has limbs driven by inverse kinematics, a flexing spine, and a tail that swings with inertia. The background is a multi-layer parallax dawn woodland meadow, and falling leaves and dust kick up at its feet. The screen recording compares Opus 5.5, Sonnet 5.5, and two GPT models on the same prompt, and it's a good reference for animation intros and creative coding demos.
