I've seen Fractint (V.14) and it's a neat piece of 'stone soup' code, with
lots and lots of different Mandelbrot types, and support for many of IBM's
weird and wonderful resolutions.

However, I haven't seen a version for the Amiga.

There are other programs though.

'MandFXP' by CygnusSoft (now released into the Public Domain, I believe) is a
capable Mandelbrot and Julia set program. Has some neat optimisations, and can
save/load piccies (including coordinates, so you can abort a calculation, save
it, and then later on reload the picture, and restart calculations).

Another program you might seek is 'MandelBlitz' by Nico Francois. This is also
PD, and uses an 'edge detection' technique with colour fill, instead of 'find
each pixel'. Nice and fast, especially on a 68030/68882 combination.

There are sundry other Mandelbrot programs for the Amiga, but they're the two
that *I* like best.
