It looks like a start to a remake of the visualization plugin for Winamp, Milkdrop2. Apparently opensource now. https://sourceforge.net/projects/milkdrop2/ https://sourceforge.net/projects/milkdrop2/ There's many many presets/scripts made for it. http://ghostco.de/milkdrop_pack/ http://ghostco.de/milkdrop_pack/ https://www.youtube.com/watch?v=zdL_JSsY6qo https://www.youtube.com/watch?v=zdL_JSsY6qo https://www.youtube.com/watch?v=VoshHRG1Qbk https://www.youtube.com/watch?v=VoshHRG1Qbk I see someone started to port it to the web: https://github.com/gattis/milkshake https://github.com/gattis/milkshake (though it did not work for me in chrome.) Edit: here's one that works, you can edit the presets: https://butterchurnviz.com/ https://butterchurnviz.com/
