Hi Chris, I followed the original discussion on HN. I found your work to be very worthwhile. I've been working mainly in clojure lately, and using Incanter for statistical applications, but I hadn't tried any simulations. Inspired by your work here, I've reimplemented it in clojure/Incanter form at https://github.com/bwanab/basic_income. Thanks for pushing the button.
