Electronic music with Nyquist?

I’m curious as to whether anyone has developed an electronic piece in Audacity from the ground up using generator plug-ins. I’m also wondering if there are any plug-ins for the evaluation of mathematical expressions which can create/modify sounds. Very impressive music has been produced this way in Goldwave, and I’m wondering what directions have been taken with Audacity in this arena.

This abstract composition was mostly generated by Nyquist in Audacity: https://soundcloud.com/stevethe-fiddle/metal-fish

I believe that the stand-alone version of Nyquist (http://www.cs.cmu.edu/~music/nyquist/) is used on the computer music course at CMU, so I’d bet that many compositions have been written there.

For a very general tool there is the Nyquist Prompt effect: http://manual.audacityteam.org/o/man/nyquist_prompt.html
