| Always nice to see people using some of the more advanced features of the
scripting abilities.
Looking over the code, I did see one little oops - you attempted to
initialize revolutions to 1, but you spelled it revolutons, not revolutions.
So technically revolutions is only assigned by the call to GetString, and
you have an unreferenced variable called revolutons.
That is all just nitpicking though. Nice work.

Not such a bad mistake. There are people selling term papers
with revolutons as a misspelling :)
http://www.radessays.com/viewpaper/...Revolutons.html
I don't think much of the English or the logic in the paper
either, which is not a criticism that can be leveled at John :)

Here's something you can do with it.

Oh, I'm sure that is it!!! Perhaps Joëlle will confirm. It makes our
job even more difficult when you start designing your own flowers.

If you wish to start compiling a library of theta flowers for future ID
purposes, here's another one:

or shorter link in case it wraps:

Not as nice as Spandex's, however :-)

Very neat, John. Can't wait to play with this one. I see Spandex has
already done a lot of nifty things with this script. Thanks!
