The Noisy applet uses the GridAreaCA class, (which is derived from GridAreaTwo) and the MyFont custom font class to produce a
rule-based interactive text hack. "Noise" is added to the text field
as keys are typed by employing a simple cellular
automata system related to
Conway's Life, a classic example of emergent behavior.
Type text in the black text area. Drag the slider up and down to
change the frequency of the C.A. update.
