David, Friends, I used Fractint's evolver on Jim's March 4th, 2011 FOYD (Emerald) and created 81 thumbnail-sized variations on his fractal. It's on the FOTD site named E110304A.gif in the "Hal's Variations..." (far right column) of the March 2011 FOYD web page at: http://www.emarketingiseasy.com/TESTS/FOTD/jim_muths_fotd.html This fractal has a lot more parameter space left to explore... While we're on "interesting things to try," try putting these two images in adjacent tabs in your browser: http://www.emarketingiseasy.com/TESTS/FOTD/F110308U.gif and http://www.emarketingiseasy.com/TESTS/FOTD/F110308T.jpg (make sure you maximize both of them by clicking each image once!), then move the focus between the two tabs with: <ctrl><pg-up> and <ctrl><pd-down> to see the effect of anti-aliasing and sharpening on this variation on Jim's March 8, 2011 FOTD. - Hal Lane ######################### # hallane@earthlink.net # #########################
