The article is interesting, but it's very difficult to read with that background. Also, my slow netbook becomes very slow rendering it.

It is definitely written for a faster computer and larger screen, however the animations are worth viewing properly.

The Julia set slideshow/animation (36 steps) is really the best part, the animation of the set "folding" (square every point) is great.

WOW! The masthead alone is worth a scroll, you even get an achievement badge. LOL

You would like the article on how they made it http://acko.net/blog/zero-to-sixty-in-one-second/ All of their MathBox-powered articles are wonderfull really.

nitpick: He not they. [0] Steven is also the person who developed MathBox. [1]

More than being an intro to Julia fractals, I think this post is a great introduction to complex numbers and functions of the complex plane[1].

The way this is presented is very similar to how most math-folk I know picture these concepts in their head. This is probably one of the toughest things for beginners, who don't understand that (most) math-folk think in pictures like this and not in symbols.

For example, starting at around Slide 29 in the first visualization, the author actually paints a picture of a branch cut[2] without using that term.

Likewise, starting at around Slide 12 of the last visualization, the author hints at the special relationship between complex numbers and differentiation in the complex plane. The jargon-y stuff involved here are holomorphic functions[3], the Cauchy-Riemann equations[4], and the very surprising-but-central theorem of complex analysis: Cauchy's integral theorem[5].

  [1]: Functions from ℂ to ℂ are "hard" to reason about because there
       are 4 dimensions involved, at least if you're picturing ℂ as a
       2-dimensional plane.

Thanks for adding more information, but that's a perfectly cromulent use of the word they.
