Prototyping

Most of what I build starts as a prototype. Before an idea becomes a system it is a question: does this hold up, how does it behave, and the fastest way to answer is to build a small version and look at it. The repositories below are that habit in the open: research code that reproduces every figure of a paper, teaching demos that make a neural network or a multi-agent system visible, and interactive explorers for vector fields, pattern formation or transformer attention. Each one was built quickly, kept small, and shared as it is.
