azuredrake writes "According to GameDaily, EA today released a free download of a Spore prototype known as 'BIOME.' The download site describes BIOME as a program that 'uses a language based on chemical stoichiometry.' It goes on to note that 'cells in a BIOME simulation change state the same way that chemicals change when exposed to other chemicals. Systems such as this can be used to simulate phenomena such as forest fires, disease epidemics, animal migration patterns and crystallization.' Note that the link provided in the article is, in fact, incorrect. Here is the correct link. Apparently, many more prototypes giving insight into the dev process of one of the PC world's most-hyped games will be posted in the future, so keep an eye on it."
