Module to calculate Mandelbrot Fractals First: you need to install Module::Signature, if you haven't already. Then get my key (http://bloodgate.com/tels.asc) and unwrap this package, then verify the contents by: cpansign --verify If the signature is valid, proceed. If the signature is B valid, do B proceed. Your system might get compromies. Please inform me ASAP. When the signature was okay: perl Makefile.PL make make test sudo make install If not all tests passed, please inform me. This module is used by an example inside the SDL::App::FPS package, make sure you check it out to see the Mandelbrot Fractal in action :) Please send me test-reports, your experiences with this and your ideas - I love to hear about my work!
