FigTree explores the iterated function y = r * x * (x - 1), also known as the logistic equation. Press and drag on the x-axis to set initial x-input. Press and drag on the y-axis or the top of the curve to set initial r value. You can also use the control panel to set values and iterate the function. If you download the applet, you can output its values. The chaotic values of the equation (when 3.57 < r < 4.0) can be used as a number source for music, etc.
