The source code and sketch data for every project on this site is available in this GitHub repository. Each folder contains one .pde file and some contain a data folder which contains the images the sketch uses. Each .pde file is exactly the same as the .pde file fed into processing.js to create the page on this website. As I mention on the "About" page, most of these projects were initially created in the Processing IDE and later adapted to be compatible with processing.js. I'm uploading the processing.js compatible versions because, in most cases, I made substantial changes to the projects after converting them to improve usability.
