What you can do in Tiamat: - Explore Conway-like cellular automata with wrapped, borderless fields. - Create, edit, save, import, and share rules with BS, SB, and HROT rulestring support. - Paint cells by hand, place saved patterns, or generate random fields. - Customize gradients and fading to make simulations easier to read and more beautiful to watch. - Save favorite worlds, layers, rules, colors, and patterns for later experiments. - Learn cellular automata concepts with built-in help and changelog articles.
