This looks like very interesting project, but I am totally confused by its licencing. According to Freshmeat summary, it is GPL. Details on freshmeat list free for educational, home and private use, while the website only has 'Freeware für private Nutzung' with a link to a license that only confirms that.
Spider Algorithm, complex dynamics
There used to be a program around demonstrating J. Hubbard's spider algorithm for the Mandelbrot set. I think it was called something like "spider". I tried to google it but to no avail. Anybody has any idea what happened to it and if it is still available?
Also, does anybody know of an X11 program that would do things like display the orbits of points under iteration, together with some statistics, in other words something targeted more towards exploring the complex dynamical systems behind these sets, rather than drawing pretty pictures?
