A magazine has expressed an interest in doing a 3-part series covering the same themes as the book.
This is great and I hope will widen the audience - more people appreciating the magic of the Mandelbrot set and it's quite exciting mathematics can only be a good thing.
The challenge will be change from the book's 3 part structure (maths, code, more ideas) into a different form which introduces the coding right from the start. Understandably this is needed to ensure the articles remain relevant to the primairly computing audience.
