myKnowledgeExplorer (mKE) is an intelligent knowledge base assistant. All communication is in a user-friendly, English-like language called mKR. mKR is designed to help human beings work more intelligently. mKE command line options include language definitions for RDF, OWL, CYC, and SUMO. mKR scripts may include embedded calls to the Unix shell. mKR gives special emphasis to context hierarchies, genus-differentia definitions, n-ary relations, questions, and action/methods.
xlife is a laboratory for experimenting with cellular automata. It supports loadable rulesets and palettes, different topologies, and up to 256-state cellular automata. It has rules and patterns for Life, Brian's Brain, Perrier's Loops, Langton's Ants and Loops, Wireworld, E.F. Codd's 1975 UCC automaton, some Prisoner's Dilemma games, and many others. It is very fast for step-by-step mode, bounded grid, and chaotic patterns. It has several unique features: a historical mode, a pseudocolor mode, and n-state statistics. It has been developed since 1989. The modern version of Xlife began its history in 2011.
