John Conway's Game of Life

Hey guys,
i have programmed the simulation Game of Life in Java. I have also added some new features like buttons to change the speed of the simulation.
It’s an applet and you can start it here : http://www.matebox.bplaced.net/programming/game-of-life/

What did you think about it?

It needs the ability for the user to add live cells.

That’s a good idea.
