This is not part of Krokodove (but resides here by lack of better home for now).

A free and open source plugin for Fusion which creates weird and wonderful (pseudo) three-dimensional fractals. The plug-in is based on the original source code by Scott Draves (1993) and Andre B. Davidson (1999). It’s open source, it’s free, … and it can be terribly slow and beautiful. What more do you want?
