Mandelbrot applet screen shots

 

Here's the applet in its default view. Notice the hand cursor also displays the complex coordinate that it's over.
The rendering engine uses the very fast Mariani-Silver algorithm. Even so, rendering can take a while, so the applet reports its progress in the upper left corner.
One can scroll by dragging the image.
You can zoom in or out by clicking the (+) or (-) buttons in the upper right. Here we've zoomed out, and the applet is just beginning to fill in the missing portions of the image at its new zoom level.
