Fractice

Fractice is a free, open-source fractal explorer/renderer for XP/Vista/Win7. Its basic features include navigation, previews, history thumbnails, antialiasing, bitmap export, printing, palettes, and undo/redo. More advanced features include deep zoom, movie recording, posters, color cycling, batch rendering, and job control. The fractals currently supported are the Mandelbrot and Mandelbar sets, including cubic and higher-exponent variants, and the Newton.

Fractice is multithreaded and utilizes all cores on a multicore machine. Fractice also supports distributed processing, using any number of additional machines as rendering servers. Distributed processing is supported for exploring, as well as for movie and poster rendering. A 64-bit version is available from the home page.

Fractice also has VJ-oriented features, such as mixing between two fractals, mirroring with origin motion, palette tweening, DirectX full-screen Exclusive mode, dual-monitor support, and MIDI control of all parameters.
