This is a Complex Lissajous Figure Generator (and Colorer) used to create Abstract looking perfectly tiled Background Images. I Didn't need the Manual (I probably won't) but I Am an Audio/Electronics Technician and I recognized Lissajous Figures right away!

3 audio signals are mixed together and combined to create the overall left/right movement of the pen while 3 different audio signals are mixed together and combined to create the up/down movement Component of the pen. The pen traces a Complex repeating pattern which you can then color in. Kind of like a Spirograph ....

You will need the Manual: but It's Quite fun to alter things and See what happens ...

Recommend to the Developer that all 3 Sub-oscillators on Both X and Y axis be allowed to be switched from Sine to Triangle or Sawtooth or Square or Pulse waveforms. Implement ONE waveform on ONLY one Sub for each axis to start with and add extra Wave Shapes and extra channels as you go along.

Also: would like to hear the mixed Waveforms in the Speakers: horizontal in the Right Channel and Vertical in the Left Channel.
