My (non-Python) plug is for "Fractals Visualization and J" by Clifford A. Reiter. This is a second edition of a book of math visualization explorations using the J language - which is a terse but interesting mathematically (executable symbolic math) oriented language that has apparently been around some time. Despite the book's name, it covers areas well beyond fractals. Site is http://ww2.lafayette.edu/~reiterc/j/ I expect it to stimulate some ideas for extending PyGeo, my geometric visualization tool created in and scriptable with P(ython). Art
