If you ever wanted a Windows version of Fractint that has feature parity with the DOS version and XFractint, here's FractalForge. https://github.com/platypuscreations/FractalForge/releases

Also has Linux and Mac versions, with both an msi installer and portable versions for Windows.

Not mine, just sharing the work of the person who did this, without using any Fractint source code.

Orbit trap coloring is always fun to experiment with. Here are some variations. These are all Mandelbrot set images.

Max Iter's Fractal Follies for October 18th, 2010

Roger Alexander's commentary for the image:

A dark moody palette with a flickering of light. This fractal was generated with a real p1 (bailout) of 20 instead of the suggested 10^12. At the usual http://maxitersfractalfollies.blogspot.com.

This is a Julia set, but instead of using just z = z^2 + c, it uses z = z^p + c, where the power, p, cycles through {2, 2i, -2, -2i}, so the same power is used every fourth iteration.

Jim Muth's Fractal of the Day for October 19th, 2011

Jim Muth's commentary for the image:

FOTD -- October 19, 2011 (Rating 8)

Fractal visionaries and enthusiasts:

For today's image I turned to a built-in Fractint formula, the type=manzzpwr, a formula I rarely if ever bring up, which on every iteration raises Z to the power of previous Z then adds Zⁿ. In today's image 'n' equals -12. After a few minutes of tweaking and experimenting with the formula, I turned up today's image, which for obvious reasons I named "Mandala-Head". The image resembles one of those surreal paintings by Rene Magritte in which people have things such as apples where their heads and faces would be expected. Today's image has a mandala instead of a head.

(A mandala is a devotional symbol representing the eternal cycles that fill the universe, especially the cycle of birth and death believed in by most eastern religions but considered heathen doctrine by the western religions, where the doctrine of only one chance to achieve salvation is accepted as truth.)

Most of the image's effect was achieved by rendering the scene with both the inside and outside parts set to 'atan'. The peach-turquoise color scheme adds to the effect, since the peach areas somewhat resemble the color of skin.

The rating of an 8 might be a little liberal, but why not, since today I'm in one of my more liberal moods. And there will be no trouble at all with the calculation, since the time is a fireball-fast 25 seconds.

The day began with clouds and mist here at Fractal Central. The foul weather continued for the rest of the day, never quite dry and never quite wet. The fractal cats approved of the temperature of 66F 19C, but Cassie approved a bit too much when she took her claws to the upholstery of the new chair and got herself scolded.

The humans had another near normal day, with nothing out of the ordinary to report. The next FOTD will appear in 24 hours.
I'll leave it to the individual fractalist to figure where it will appear from. Until then, take care, and if reincarnation is true, then about half the people on earth hold false beliefs; if it is false, then the other half hold false beliefs. In either case, the religious beliefs of at least half the people on earth are false.
