I am a big fan of Processing and Generative Design and yes learning the software would be on top of my bucket list – if I would have one. The software is free to download and you can use it right away via processing.org – there are a lot of tutorials and examples on the site. There is a new documentary that could be a perfect intro into the theme of processing.
Hello World! Processing is a very nice documentary on creative coding with a lot of examples that explores the role that ideas such as process, experimentation and algorithm play in this creative field featuring artists, designers and code enthusiasts.
If you like the video, you may also like this book: Generative Design.
The website completes the book Generative Design. It offers direct access to all processingsource code for the software described in the book. Very nice!
