The main entry point is in joy_vis.pde, which contains the setup() and draw()functions. Processing calls setup() once at startup and then draw() once every frame.
joy_vis.pde - Main entry point, contains main drawing loop
JoyLine.pde - A class defining a line to draw, contains an array of JoyPoints

JoyFFTList.pde - A linked list class defining a list of JoyFFTLines.
JoyFFTLine.pde - A class defining a sinlge FFT line. Contains the FFT values of the incoming audio, transformed into z-values ready for plotting.
