Open Source C Command Line Tools for Linux

FractalNow provides users with tools to generate pictures of various types of fractals quickly and easily. It is made of both a command line tool, FractalNow, and a graphical tool, QFractalNow. The graphical tool, based on Qt library, allows users to explore fractals intuitively and generate pictures. Both tools are entirely multi-threaded and implement advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators.
