Heads U... Software I use,,

Windows:

Fraxplorer -  (KPT Power Tools) Photoshop plugin / Mandelbrots and Julias
MBF - Paul Carlson's Baby... Still the Most Fun of any of the standalones...
Ultrafractal - For me the best allround Fractal app in town (but it aint free) - lends itself nicely to custom formulae, colourings etc and the above mentioned fun Paul Carlson Colourings
Apophysis 7X - Flame generator
Fractal Explorer 2.03_b2
Tierazon
VChira
Sterlingware
GrafzVizon
Inkblot
Flarium
Mandelbulb3d
Incendia
XaoS
