This is slightly off topic but...

I took scheme in college, and promptly forgot it after the class was
over since I was much more interested in C++ at the time.  I've come
back to scheme now, and I think I've come to really like the elegance
of the language.  The problem I'm having is, unlike many other
languages I learned, I'm having problems finding and learning the
idioms beyond the basic ones. I'm having a problem finding examples to
advance to the "next level".  Are there any pieces of
code/projects/books that any of you would suggest which would give
comprehensive examples of idioms and even styles.
