Basically what's happening here is that a sprite goes over each pixel on the canvas, runs the equation for a set amount of iterations to determine the color of said pixel, and draws the pixel. For the sake of your sanity, shift-click the green flag first so it speeds it up.
Very cool fractal derived from the equation f(z)=z^2+c. (C doesn't mean constant of integration here, it represents the imaginary portion of the complex number.) This equation is what's being visualized in this project; if the coordinates of a pixel (translated into the complex plane) are in the Mandelbrot set, it's given a dark color. If not, it's given a lighter color. The gradients are caused because, though it's not in the actual set, it's closer to being in the set than others.
