Golly is an open source, cross-platform application for exploring Conway's Game of Life and other cellular automata. Golly's key features: - Supports bounded and unbounded universes, with cells of up to 256 states. - Supports multiple algorithms, including Bill Gosper's super fast hashlife algorithm. - Many different types of CA are included: John von Neumann's 29-state CA, Wolfram's 1D rules, WireWorld, Generations, Langton's Loops, Paterson's Worms, etc. - The RuleTable and RuleTree algorithms let you plug in new rules. - Responsive even while generating or garbage collecting. - Reads RLE, macrocell, Life 1.05/1.06, dblife, and MCell files. - Can also read common graphic formats: BMP, PNG, GIF, TIFF. - Can extract patterns, rules and scripts from zip files. - Can download patterns, rules and scripts from online archives. - Includes a state-of-the-art pattern collection. - Can paste in patterns from the clipboard. - Unlimited undo/redo. - Configurable keyboard shortcuts. - Auto fit option keeps patterns sized to the window. - Full screen option (no menu/status/tool/scroll bars). - Supports multiple layers, including cloned layers. - HTML-based help with an integrated Life Lexicon. - Scriptable via Perl or Python.
