Fractal Factory

Hi, all.

Sorry to be a nuisance but I have not recieved any responses regarding
Fractal Factory. Surely at least one person has used the program to some
degree and is willing to criticize?  Perhaps I can assume the program is
perfect in every way...

Not! already some bugs have been squashed and FF is now 0.9a rev 1.
Soon to come in 0.9b is some new basic fractal types. One is something
really weird, fondly known by some as an MRCM (Multiple Reduction Copy
Machine).  This creates something like video feedback in real-time,
transforming any image into different fractals like the sierpinski
gasket, kosh curve and theoretically almost any other type I think.
The (basic) Lyapunov fractal type should also be included.

-- re: abs function --
These are the algorithms I use for abs (and sgn, another function I find
useful). They work for sequences as well as atoms.  I don't expect it's
the fastest solution but should certainly be faster than invoking sqrt,
as was suggested earlier.

function sgn(object r)
  return (r > 0) - (r < 0)
end function

function abs(object r)
  return r * sgn(r)
end function
