In my last post , we played The Chaos Game and ended up with a Sierpinski Triangle. It’s quite nice as far as it goes, but there is not a lot of variation and visual interest beyond the initial surpise of finding it buried in the chaos at all. This time around, lets look at the de Jong attractor. First, some terminology! An Attractor is a dynamic system with a set of numeric values to which the system tends to evolve over time, no matter what state it starts in.

Today, we’ll play The Chaos Game! It’s easy to play, and it goes like this: First, put three points on your paper. These will be the vertices of a triangle (so don’t put them in a straight line!) Any triangle will work, but be sure to leave lots of area inside where the triangle will be to make it easier to see what it going on. Next, you need a way to randomly choose one of those vertices over and over.
