It's too bad they do an arithmetic version. If you do it by hand, going the geometric route is much more fun.

You can interpret the squaring and adding as geometric operation to be done with ruler and compass. If I'm not too lazy, I might write a blogpost about how to do it.

I'd appreciate such a blog post.

I've used the geometric route for drawing Julia sets, but I don't know how you would do that for the Mandelbrot set, what with a different constant being added for each point and all.
