A Conway's Life application for *nix. GtkLife is an implementation of Conway's Life, a cellular automaton (grid-based artificial life) developed by the mathematician John Conway. It features a highly optimized algorithm for computing generations, a giant universe (1 million x 1 million cells), and a modern, user-friendly interface. Example patterns are available from an optional sidebar on the main window. The user can also draw their own patterns, and load and save files in a number of popular Life formats.
