Fract-O-Rama is a Qt-based fractal generation program. All fractal images are specified using the program's fractal scripting language, so it is possible to explore a wider variety of fractal types/options than with many other generation programs. Full source is included, and the program readily compiles/runs on UNIX or win32 (win32 binaries are also available, as a Qt commercial license is required to build the program on windows). It comes with documentation and many example fractals.
