Okay...eleven days later and I've finally got something that works!
You can find a fully working Clojure version of GraphEditor.java at

Clojure beginners, there is a lot you can learn from comparing the
Java and Clojure versions of this program (though Clojure progra

Don't be too hard on yourself - it takes a while for the clojure
patterns to sink in so you easily spot the simple errors. Best to
throw it out there so someone else can help.

Alex wrote you before: :extends does not take a vector.

Maybe you can make it a normal clojure fun
Alex, thanks for your two posts and for taking the time to look at the
original source code. Some comments:
Re: Integer being final. Actually, I remembered that...and then
forgot. Tired? Clueless? You decide.
I'm going to fold your observations into a new test program to see
what happens; thanks.

Hi--another example, another failed attempt to do something that looks
quite basic (grumble, grumble) ...
I'm continuing on my path to learning how to use Clojure with the
graphics library Piccolo2D (http://www.piccolo2d.org) by re-
implementing some of Piccolo2D's sample programs. Now I'm working
