Baker's choice. Dense with flavour, light on filler.
Summary
Ballin is a terminal-based physics simulator written in Rust that displays thousands of colorful balls with realistic physics using Braille Unicode characters. The project was developed with AI assistance (Claude Opus 4.5) to explore whether Braille characters could effectively simulate complex ball physics in a terminal environment. The application creates a visually engaging physics simulation within terminal constraints.
