This first applet is Conway's Game of Life, programmed by Kyle James.
For an explanation of this program and some interesting illustrations, see the
Wikipedia article at
http://en.wikipedia.org/wiki/Conway's_Game_of_Life. The Java program is interesting
because it requires the manipulation of thread states to implement the Run and Stop
buttons.
This second applet is a Minesweep game, programmed by Todd Hurst.
