How it Works

\n Organism Representation: Each circle on the grid is a digital machine\n with state variables (energy, genome, etc.).\n
\n Energy Flow: Green cells represent resources that organisms consume to\n gain energy. Energy enables reproduction and movement.\n
\n Interaction & Evolution: Organisms move randomly, pay a movement or\n idle cost, and gather resources. Once they reach an energy threshold, they reproduce.\n Offspring may mutate, leading to new genome strings and color changes.\n
\n Machine Principles: Each organism continually converts resources\n (energy, matter, information) into self-maintenance and new machines (offspring). This\n leads to evolving behaviors over time.\n
