Up to now, there has been some interest in my Mandelbrot Art. Some of the images have appeared in print (or used otherwise) in:
"Invariant Magazine" (front page, Issue 16, 2005) of the Student Mathematical Society "invariants" of the University of Oxford, and has a comprehensive article on "Drawing the Mandelbrot Set" (by Martin Churchill, on page 27; info at email@example.com).
This page is also available in a Lo/No-graphics version. If some of the text on this page is difficult to read, also look at the Lo/No-graphics version.
Large Cleft between major bulb and first minor (89kB)
Different Zooms at the left side of the cleft (the 'Dragon' area):
(127kB) Big (2048x2048, 804kB)
Progressive Zooms at the right side of the cleft (the 'Seahorse Valley'):
Antenna at the left side of the full Mandelbrot Set (85kB)
Antennae at the top of the Mandelbrot Set
(87kB) Big (2048x2048, 519kB)
'Mandelbrot mountains' can be made by using iteration counts as elevation. All mountains here are made from the whole Mandelbrot set. In the second and third pictures (the gradient-shaded ones) a special feature of the Fractint program was used to create a smooth gradient inbetween iteration counts. This is called the 'continuous potential' function and interpolates iteration values based on the magnitude of the first complex number that escapes to infinity. These values are stored in 16 bit accuracy (actually 8 bits integer with 8 bits 'interpolated accuracy') and used as elevation levels.
FractInt can also wrap a picture on a sphere, using colour data as a depth or highth from the surface of the sphere. Adding the right colour-scheme, this results in moon-like objects:
I am planning to add some more info to the pictures, like the area, zoom factor maybe a description of the colours-schemes I used and maybe point out some exceptionally interesting features in some pictures..
