A flash version of the ever amazing "Game of Life" (http://www.bitstorm.org/
gameoflife/) Just draw and watch it come to life!
--INSTRUCTIONS--
Click on the little COG next to the "Game Of Life" title to get the OPTIONS PANEL. The CROSS clears the playing field and the START and STOP buttons start and stop the evolution (well, obviously!).
CLICK on the cells to toggle whether its POPULATED or not.
----
--EDIT--
Added new part in options panel to modify the rules that are used in the game of life to create some really weird patterns.

Have fun!
