Description

A p5.js-based simulation featuring a ball bouncing within a spinning hexagon with realistic gravity, friction, and wall collisions. The interface includes a neobrutalist design with real-time sliders to control parameters like rotation speed, ring size, and impact sparks, demonstrating the one-shot coding capabilities of the Step 3.5 Flash model.
