<p>This is the classic Conway's game of life. Set up your initial pattern by filling

in cells and then press run and see what evolves! There's only a few simples rules.

<ol>

<li>A living cell with fewer than 2 neighbors dies from loneliness</li>

<li>A living cell with more than 3 neighbors dies from overcrowding</li>

<li>An empty cell with exactly 3 neighbors becomes a live cell.

</ol>

The main game board is on the left. If you find a configuration that you like,

you can copy and paste it into the pieces box. Click on pieces and then paste them onto a gameboard.

The universe wraps around on both the sides and the top and bottom. Cells painted red lets you know you're

seeing a part of the universe that has wrapped around
