Twelve package-powered experiments

From living postcard to matter sandbox

Creative tools, scientific experiments, games, instruments, and rule search—ordered by implementation and interaction complexity.

Every page consumes the published package @hexlife/embed@1.7.1 binary · k-state · renderer · grid · exact world codes

Start with a single editable world and move upward through custom transition tables, host-owned interventions, paired deterministic experiments, scoring, sound, population search, and multi-material reactions. Every card opens a dedicated application with its own controls and measurements.
