Cellular implements Conway's game of life with the original rules. A cell is either dead or alive. The following rules define the next state of each cell. Any cell with less than two neighbours dies for loneliness. So does a cell with more than three neighbours because of overpopulation. A cell with exactly three neighbours will get alive.
Use the simple arrow to simulate a single step or the double-arrow for the loop mode. Pause with the double bar and stop the with the square. The broom clears the matrix and the dice sets it to a random initial state. The pin saves the current state which will be reloaded by stopping the simulation. Tapping a cell in the matrix toggles the state
The size of the matrix and the simulation speed are set in the settings.
