Hi Frank,

Could you let me to know fuller details of that book(s)?

Your program if a very "full" one, much more developed than mine - of
course. I think that I could understand the function of each slider and
knob. What interests me is more the programming tools than the intricate
artistic image, but that's only my side - of course.

My needs, and programming style, dictate (real) recursion for creating
tessellation's.

In any case, don't expect it to be a short program...

Good luck and enjoy your Logo,
