Playful thinking
I found these beautiful images at http://en.wikipedia.org/wiki/Newton_fractal. Naturally I would like to create them and play with others. But where do I find free PC software for this? Do you know?

A cursory Google search reveals:

From the last link above, I’d try Fractal Explorer.

Due to the many links it thought your comment was spam. If you hadn’t told me, it would never have been published. (:
Thanks for the links! Time to play!
