The first examples in Code Snippets were ported over from the Processing Hacks website set up by Tom Carden and Karsten Schmidt. Thank you gentlemen and all the original Hacks contributors! These examples were moved over by Casey, the week of 7 June 2010. The categories were cleaned in the process.
There are other great resources online for finding more Processing source code. Most notably, OpenProcessing is an active community of people sharing code.
If you maintain an archive of code examples, please feel free to add them here, to OpenProcessing, and/or to link to them below.
