OWASP Top 10 Demonstration Code

I'm going to be a guest lecturer for a computer science web application
development course later this semester. I was wondering if there was a
set of demonstration code specifically linked to the OWASP top 10. I'm
aware of tools like WebGOAT, HACME Bank etc... I've used a number of
such all in one sites to test tools or practice my technique. However I
was wondering if there were specifically something designed for
demonstration rather than practice. More importantly it should include
all of the issues noted in the OWASP top 10 if possible.
