Mandelbrot
A fractal generated by continuously squaring a number to see if it eventually approaches infinity or zero. If it approaches infinity, it will be lighter. Black pixels are zero.
You can view the Mandelbrot page here: Mandelbrot. When using the application, click and hold down the left mouse button to drag a rectangle. The area in the rectangle will be used to calculate a new fractal, zoomed in to that area. It gets increasingly difficult for the computer to process as you zoom in. I've capped the number of iterations to 2000. This means your computer will stop trying to determine if the fractal goes toward infinity or zero after 2000 iterations. Still, 2000 iterations takes some time, so be patient after you zoom.
