Ciggles

In addition to wiggles and twiggles, there are also ciggles: or curved twiggles.

Here's an example of a sequence with twelve distinct segments, where each segment is a ciggle.

These plots are from an 80-second transformation; the plots are about 20 seconds apart. Next to each state is its FFT. You can see that, indeed, the timbres do change.

This 80-second example sounds like this. Please note the changing harmonic envelops.

Sound example 7: 80 seconds
