 |
- Includes Eight classic cellular automata
- Beautiful TUI navigation menu
- Real-time speed control with up/down arrow keys
- Focus mode for distraction-free fullscreen viewing
- Monochrome toggle for terminal theme compatibility
- Generation-based coloring creating trippy wave effects
| Automaton | Description | Alias |
|---|---|---|

| Brian's Brain | 3-state automaton with beautiful trailing patterns | brain |
| Langton's Ant | Simple ant following two rules creating emergent complexity | ant |
| Larger than Life | Generalized Game of Life with extended neighborhoods | ltl |
| Belousov-Zhabotinsky | Chemical reaction simulation with spiral waves | belousov |
| Faders | Multi-state cells that fade through colors before dying | faders |
| Forest Fire | Trees grow, catch fire, and burn in natural cycles | forest |
| Wildfire | Stochastic fire spread through vegetation | wildfire |
