I have problem with point size. I use diffrent positive integer values
but points are still small.

Can you expand it ?
Do you think about drawing only array Hits in 3D.
It would be an diagram like fig 27 in "the beauty of fractals" by Peitgen.
Can you do it ?

Yes I will do it.

Yes I know it. These packages inspired me to use Maxima for fractals.
Dynamics is in Lisp so I have a time to learn it, because I would like
to add new functions , not only use it.
There are many unsolved problems. Help is wellcome.
