I once calculated the Mandelbrot set on graph paper. This article makes me feel slightly less dorky. :)

Super cool! Did you know about the Monk who did that hundreds of years ago? Except it was a hoax.

I didn't know about that, neat! In fact I'm rather proud to say I couldn't have known about it at the time, because it was... hmm... I'm gonna say 1993, give or take a year.

My version had considerably lower resolution, though, since I used quarter-inch grid paper at 8.5x11", so it was 0.125 units per square. :)

Meanwhile, look what I just found while verifying my memory that the core set fits in y = +/- 2.0:

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.
