UPDATE - I've enrolled the book in Amazon's KDP Select so it'll be offline from Google and Nook for 90 days.

Animated Journey Deep Into the Mandelbrot Set
There's a great video on vimeo animating an interesting journey down into the very deep depths of the Mandelbrot set.
The music is great too - really makes it an atmospheric mystical voyage!

Now on Nook
The book is now also on Barnes and Noble's Nook store.
They have a file size limit of 20MB so the epub had to be shrunk a little, I hope the smaller image files aren't noticeably different.

Sharing the Code
I was asked to share the source code so that readers wouldn't have to type it all in themselves, something that potentially introduces errors.
I've shared the wakari.io IPython notebooks so you can view and run them, and copy the code as you please.
Mandelbrot fractal: notebook
Julia fractal: notebook
3D Mandelbrot lanscape: notebook
3D Julia landscape: notebook
Sobel image filtered Julia set: notebook
Have fun!
PS. I remember the old days of typing in code from computer magazines yelllow pages, puzzling over the typing errors, and learning quite a lot from doing it actively. I'd still recommend you follow the discussion in the ebook.

Writing for a Computer Magazine
I'm writing the magazine articles as a 3-part series. It's a real challenge to squash down the size of the books content to 3 sets of 2400 words, the book itself wasn't too florid in it's language.
More challenging is trying to move away from the clear 3-part structure of he book (concepts, DIY, extensions) to 3 articles which must all contain significant elements of programming because the magazine which might publish them is a computer magazine. You can't ask readers to read an entire article on mathematics and wait another month before starting any Python.
So I think this will have to have programming using IPython as the primary focus, with the exciting mathematical journey taking a less prominent role. Sigh.... the sacrifices!

Proofreading
Despite months of writing and checking, and rechecking, it turns out that someone else who does proof reading for you will spot things that you've become blind to!
As a result I'll issue an updated ebook to Amazon and Google. If you've purchased the books already you should be able to get updates automatically at no extra cost.
As ever, if you make significant contributions to the book, you'll get the next edition free.
UPDATE - I've updated both Amazon and Google's stores with the latest round of corrections. I'm trying to get the book into Barnes and Noble's Nook store too.

Book is now on Google
The book is now on Google Play Books too.
It's the PDF exported from Google Docs, because the custom built PDF I was designing was taking too long.

Book Published on Amazon Kindle
The first edition of the book is out!
Make Your Own Mandelbrot [Kindle Edition]
I could have gone on forever fixing and tweaking to the nth degree, so I pulled the trigger as soon as I thought it was good enough.
Please do feed back your opinions, corrections, requests for further explanations. If you're particularly helpful I might give you a copy of the updated edition for free!
I have been disappointed with the whole epub/mobi formats and the quality and varitation in rendering across devices. Google bookshop does allow PDFs which you have much greater control over .. so I'm lookign forward to doing some nicer design for it.
