Conway's Game Of Life is a cellular automaton originally conceived by 
John Conway in the early 1970's.

Use the mouse to interactively define a starting grid by clicking on
cells in the grid to bring them to life. Clicking on a cell toggles its
live state.  Click and drag to bring a bunch of cells to life.  Live 
cells are represented with green circles.

The rules of evolution are as follows:

- If a live cell has more than 3 live neighbors, it dies from overcrowding
- If a live cell has fewer than 2 live neighbors, it dies from loneliness
- If a dead cell has exactly 3 live neighbors, it comes to life

Click the \"Evolve\" button to iterate through generations one at a time.
Click the "Clear" button to clear the grid.
