[plt-scheme] Some suggestions on nice pedagogical code

Hey there

I'm looking for some low/mid level complexity open source code in scheme
that would be fairly well written so I can point some people who want to
look at some 'real' code in the wild.

Anything would do, but it would be nice if the code kind of is a nice
representation
of a style, like "This part is mostly OO, with some AOP mixed in (or
vice versa), that other
is mostly functional, with continuations and blabla".

Suggestions?
