Neat! A while back I worked on a couple of Common Lisp projects that used the equations behind Spirograph curves to generate animations synced up to music. The results were really neat: https://vimeo.com/147813490 https://vimeo.com/147813490 And the code: https://github.com/jl2/spiro-animation https://github.com/jl2/spiro-animation I also made a GUI version that allows tweaking a bunch of settings: https://github.com/jl2/qt-3d-fft https://github.com/jl2/qt-3d-fft
