Click on a cell to flip its state, or drag to paint on living cells.
In this example, the starting state of living cells is called a “pulsar” – an example of a cyclic form with a period of 3. In other words, if you step 3 times it will return to the original state.
Click on the cells to turn them on or off – maybe you can find other stable or cyclic forms.
