I have a one pagish program that you pass in your screen resolution and it
randomly picks out a new
desktop image from ftp.gnome.org, downloads the image and updates your
desktop. This assumes
your using Gnome.

I did something similar the other week:

Using clj_web_crawler and XHtmlRenderer to make a PDF of a locally available
book (in wiki format) on the history of the New Zealand Internet.

You can do that? What do "Fix the bug while in the break" mean? I know you
could do that in Common Lisp. I'd love to know how
Speaking of "walking/filtering code," what about walking _actual_ code?
The only thing off the top of my mind would be an example of, say, a "Hello
World" function, but with the code represented as a JTree. Say, in the
function (pr (.toLowerCase "Hello World")), you'd see .toLowerCase as a
node.

I'm guessing glitz and visual impact is what's going to wow the crowd,
especially in that environment, where it's likely that most people are
steeped in "business applications".
Perhaps using one of the clojure-processing wrappers to do some
outrageously-slick data visualization, and then s

Macros
are incredibly powerful, but again, I fear that with the limited time,
quite a few in the audience might underestimate what they can provide.
One quick question: is anybody going to get this on video? I'd really
like to see how it turns out.

+1 for showing the Ant demo and modifying it while it's running.
Emphasize how easy it is to get RELIABLE concurrency using agents/STM.
As Steve Jobs has long known, eye candy counts, and Ants is an eye
candy way of seeing concurrency in action.
I would also keep a second REPL open and "test" out
i think destructuring is awesome, and loop-recur loop-recur is so handy
in not having to have the public version of a function (entry point) versus
the recursive inner version that often has extra parameters that the user
shouldn't have to worry about.

For me, persistent vectors was the killer feature that drew me to
Clojure. Don't know how to convey the value of that in 4 minutes,
though.

Whatever you chose, you probably ought to show its source with an IDE
(whichever you chose: NetBeans. Eclipse, IntelliJ) but should probably
forget about emacs: many (most?) Java developers won't even consider
anything that isn't at least partially integrated within some IDE.
