Here is a proposal for another way of picking colours in
escape orbit type fractals:

For every pixel
    If NOT coloured
        Do Until ( maxiter OR escaped )
            [Begin Proposal]
            calculate distance of calculated point z(n+1) from z(n)
            set colour of z(n+1) according to calculated distance
            [End Proposal]
        Done
    EndIf
EndFor

This is essentially an escape velocity representation of
the orbits.  Yet another variation would consist in giving
all pixels in the orbit the same colour as the last pixel
of the orbit.

There is also an interesting way of generating the image
in slow motion:

Do Until ( maxiter )
    For every pixel
        If ( ( NOT escaped ) AND ( NOT coloured ) )
            perform just one iteration
            [escape velocity colouring would fit here]
        EndIf
    EndFor
Done

Enjoy...
