"browse sketches that are uploaded onto openprocessing by external people, choose one application that you very much like, play with its code, modify it and try to understand the code, then make a blog post and describe the things you learned and the things you could not figure out. Please also post questions and ideas that came up during the process."
After browsing over the open processing website for a while to try and find a sketch/application that i thought was cool i came accross Wavy by Jared "BlueThen" C.
The code was very easy to go over and not to big, the author of the code did a very good job explaining each step and process with comments within the code. Regaurdless of all the useful comments there were a lot of parts of the code i still struggled to understand.
