A 2D table of random numbers (random "Wave Terrain") is read with a 2D sinusoidal indexing function in a Lissajous pattern.
The parameters are for the Lissajou pattern, and are in two sets, one for the sinusoid in each of the two dimensions:

Frequency         - the frequency of the sine wav
Fine Frequency  - same, but finer control
Min, Max           - the Min and Max determine the distance covered by the sine wave on the wavetable
MinMaxShift     - center of the sinewave on the indexing table in the respective dimension

Cool parameter settings to explore:
* Set the x and y frequency relationship to be nearly an integer multiple, then explore with the fine frequency control
* Set the frequency of one dimension to be near 0.
* Set a small excursion for the at least on indexing dimension (make Min and Max almost equal).

Note: You can use an external MIDI slider box for control - settings under the Options menu.
