   "description" : "Iannis Xenakis begging us from the grave: \"I need you! I need you! I need you!...\". This code is based on an example from the Help  documents that uses MouseX.kr and MouseY.kr, but I've replaced the MouseX and MouseY with a \"2d squiggle\". I wrote a blog post that explains how to generate \"2d squiggles\" like these (as well as completely different ones) - see http://technogems.blogspot.be/2017/08/automating-squiggles-in-supercollider.html . If you run the code also a scope will appear. Put it in X/Y mode to see the squiggle as it is being generated and executed.",
