Spore Prototype number 2, BIOME. BIOME is a programmable cellular automata simulator that allows users to develop simple "SimCity-like" grid simulations.
The grid-simulations in SimCity were inspired by Conway's "Life" program, which produces amazingly intricate patterns from simple rules. BIOME uses a language based on chemical stoichiometry, the notation system used to describe chemical reactions. Cells in a BIOME simulation change state the same way that chemicals change when exposed to other chemicals.
