One of my favorite circuits from Korn & Korn [0] is an implementation of an arbitrary function of a single variable. Take an oscilloscope-style display tube. Put your input on the X axis as a deflection voltage. Close a feedback loop on the Y axis with a photodiode, and use the Y axis deflection voltage as your output. Cut your function of one variable out of cardboard and tape to the front of the tube.

N-SPHERES

N-SPHERES ist the most complex Oscilloscope Music work by Jerobeam Fenderson & Hansi3D and took six years to make.

Since it is almost entirely created with parametric functions, it is possible to store only these functions in an executable program and let the program create the audio and video output on the fly. The storage space required for such a program is just a fraction of an audio or video file, so that it's possible to store the executables for the entire audiovisual EP all on one 3.5" 1.44MB floppy disk.The first 500 orders will receive the initial numbered edition with pen-plotted artwork
