flam3 3.1.1-4 (amd64 binary) in ubuntu impish

 Fractal Flames are algorithmically generated images and animations. The
 software was originally written in 1992 and released as open source, aka
 free software. Since then it has developed a lot. It has been incorporated
 into many graphics programs and ported to most operating systems. The shape
 of each image is specified by a long string of numbers - a genetic code of
 sorts.
 .
 You can create your own flames with the Apophysis interactive designer (for
 windows), Qosmic (for Linux), or Oxidizer (for Mac OS X), or Apophysis-J
 (cross-platform in Java). Or you can use the Electric Sheep distributed
 screen saver to join the collective evolution of animated fractal flames.
