Well, given that concurrency is a hot topic at the moment, how about
something based on STM?
E.g. perhaps some kind of instant messaging server? Or "Twitter" except
scalable. By ruthlessly eliminating features, you could get the core of
one of these down to something that could be built in three hours.
But please, no Santa Clauses ;-)

reverse a list", "here's what a type is" etc; you know the kind of
thing. But instead, I'd prefer to show them programs that they might
consider *useful* rather than cute, and introduce the language along the
way, as it were.

I'd like to use you as a filter: tell me your favourites, the examples
you find compelling. (It doesn't have to be *your* program... a URL to
a great blog entry is just fine.) Of course I'll give credit to the
