Oscilloscope Mushrooms using Linux Laptop Orchestra (L2Ork/purr-data/puredata), following Jerobeam Fenderson's "How To Draw Mushrooms On An Oscilloscope With Sound" (https://www.youtube.com/watch?v=rtR63-ecUNo)

Run the patch mushPanel.pd to load the presets for the steps below:

Cos(f) on the vertical, sin(f) on the horizontal

Add Sawtooth(f/n) to the vertical

A: Horizontal multiplied by sin(f/n)

B: ...but only use the last quarter

A: Sawtooth(f/n) multiplied by cos(f/n + x) added to horizontal

B: Sawtooth(f/n) multiplied by cos((f/n + x)/3) added to horizontal

Version in the Raspbian repository, 0.46.2. Doesn't work with mushrooms.pd.
