A set of those structures, you would 13 | get, has often been called ”generative art” for having both organic and mechanical in itself. 14 | If you want to create ”generative art” intuitively, this powerful language will be your best friend. 15 | 16 | 17 | 18 | ## Notes 19 | 20 | This is a javascript implementation for generating in real time in your browser. 21 | Original implementation is included in Structure Synth authored by Mikael Hvidtfeldt. 22 | 23 | ## License 24 | 25 | Copyright (c) 2013-2020 Satoshi Okami.
