MS Paint-style circuit design tool where colored pixels represent wires and logic gates. Simulates circuits in real-time using WebGL pixel shaders. Includes a functional 4-bit microprocessor with 16 memory cells, ALU, LCD display, and registers running stored programs.

Not strictly a pet project — built as part of the Braid Project. I co-designed the algorithm, designed the underlying CRDT, and built this visualization. Antimatter can prune CRDT history in an arbitrary and dynamic network topology.

WebGL visualization of Penrose tilings with infinite scrolling — an aperiodic tiling that never quite repeats itself.

A higher-dimensional variant of the Penrose tiling, projected down with 8-fold symmetry.

A visualization of spinors — showing how you can take a circle embedded in a real rubber sheet and rotate it twice around the same axis, and the sheet returns to its original state without ever tearing or being un-rotated.

Physics simulation of the XY-model from statistical mechanics — spins on a lattice forming vortices and domains.

A 3D extension of the XY-model, with spins living on the surface of a sphere.
