How to Create Mushroom Designs on an Oscilloscope Signal Detector Using Sound

Electronic musician Jerobeam Fenderson has created a video tutorial demonstrating how to draw mushroom-like designs on an oscilloscope signal-detecting machine using only sound. The tutorial does require some prior knowledge of the machine, but the results are still impressive even for the uninitiated.

Now first we need a sine wave on our horizontal deflection channel and a cosine wave on our vertical deflection channel.
