[PD] [PD-announce] recursion in Gem - a tutorial

[Steffen]

Hey Claude,

Thanks for making this slick well composed tutorial.

I have a few comments.

1) in 03_recursive_spiral.pd you start out by writing "A common idiom  
in Gem is to use the [repeat] obejct (...) Let's try using (...)".  
But in the patch it is not used. Instead you present the recursive  
method, as would hope from the great bottom up composition. Replacing  
the first paragraph whit something like "Now we draw the spiral  
without repeat, but using a/the recursive method". That would work  
with the conclusion too. I think.

2) It would be cool if the n-ary tree example could be tweaked such  
that the binary tree example would be a special case of the n-ary  
example. Maybe i'm missing something.
