Could anyone explain to me how to produce a Julia set visualization in Processing? I've seen lots of examples of code for other languages using complex variables, but Processing doesn't have that capability (as far as I can tell). I'd like to avoid using external libraries if possible. I've seen the Mandelbrot example, but I'm pretty new to the ideas of fractals, so I'm not completely confident in my understanding of it and I'm not sure how to translate that into a Julia set. Could someone also explain the difference between the two?

Thanks in advance guys.
