Life in life

Life in life

A two-minute video of Conway's Game of Life running inside Conway's Game of Life, built from OTCA metapixels and Golly. It zooms smoothly between scales.

The canonical visual for nested simulation, Turing completeness and self-reference; HN readers call it mind-blowing and reach for it constantly.
