use this tool to modulate the parameters of a 3D torus knot with an audible spectrum sound wave -- it is a toric oscilloscope.
eventually, this will function as an oscilloscope for external instruments, and will naturally handle (up to 4) polyphonic voices in a more compelling and useful way than current oscilloscopes.
it will also act as a stand-alone visual FM synthesizer, using evolving toric geometry to organically determine frequency.
the natural "mode of evolution" in the category of sound waves is oscillation; for topological spaces it is deformation. this is an early step to finding meaningful, functorial methods to compare these modes of change.
arrow keys = rotate // Enter = reset rotation // Space = play/pause animation // use the checkboxes to engage target parameters
use the first 2 keyboard rows (q-i --> a-k) to play the oscillator in harmonic tuning, or m
to play a selected frequency.
