Hello, Gerry,

Wow, Waaaaaaaaaaaaay too cool  that explanation was good but useless I am no
genius in math's - I use in built formularies. I will be hiding behind
nearest tree if you ask me to come up with something like this you just
wrote. Can I keep your letter, please? We have a few fractal junkies in my
other group and they will be impressed with it also.  But I must warn you,
their math's are just as mine - at the level of 2 + 2 = ?....

And I want to get you started on Mandelbrot or for that matter Julia, may be
I will learn something new there...

Way off topic too.

Thanks for letter.


Aunty Pear
