What is "fractint"

Fractint is a freeware computer program that can render and display many kinds of fractals. The program originated on the MS-DOS platform, but has since been ported to Linux and Microsoft Windows. Additionally Tim Gilman has ported Fractint to the Macintosh. FractInt is one of the oldest freeware programs still being maintained. During the early 1990s the program was the definitive fractal generating program for personal computers.
