I found the source to the ants simulation on GitHub, made a gist: https://gist.github.com/1494094

Note that this is pre clojure 1.0. With some of the newer features some things could be simpler (futures).

This is an old recording.

It's my favorite of the many recordings of Rich giving presentations on Clojure in the early days.

It's where he presented his famous ants program that runs on ~64 native threads.

I was in the room for this presentation, it was the first time I had heard of Clojure.
