View the high-quality gif – Get the source code
One of the sites I recommend on my tutorials page is the ‘Imaginary Institute’. I liked its ‘total beginner’ approach a lot at the time and I also had a nice e-mail conversation with Mr Glassner about Bézier curves. He had very, very helpful and detailed advice. And a lot of patience 😀
I’ve only now discovered though that he also has a Tumblr where he posts animations twice weekly. With the source code.
You should really follow that Tumblr if you’re interested in coding in Processing.
Additionally you might be interested in his article about ‘globs’.
