Below is a java version of John Conway's Game of Life. It is fairly simple to use. You can select some default starting points by using the combination box on the left of the bottom control panel. You can also add cells directly by clicking on the grid. If you click and drag, you add cells. If you simply click on the grid you will change the cell - a blank cell will be filled and a filled cell will be empty. Pressing the start button will start the program. Pressing stop will stop the program and allow you to enter new cells or figures. The clear button starts the process over.
