The latest version of MolPrime now comes with its own mini-game: Life! Old-school math-science types will be intimately familiar with this game, which was invented in 1970 by John Horton Conway. It simulates the birth and death of cells, which is determined by the number of adjacent cells in the previous generation.
In MolPrime, the starting population is constructed from the current molecular structure. In the screenshot shown here, the first generation of cells is derived from caffeine.
To create your own petri dish, draw a molecule, and select the Life panel on the bottom right. For an animated example, see the YouTube clip.
MolPrime is free, and available on the iTunes AppStore.
