I believe LightTable [0] ran with some of the concepts in the video, and I remember one of Chris Granger's videos having an almost identical bit about mapping time over space in a ball/block jumping game and very similar themes. Either way, it's definitely worth checking out. Sorry if I get any of the details wrong, I'm a bit out of step with Clojure.

[0] An IDE that supports Clojure and Javascript right now, maybe Python soon? Bit behind on the news: http://www.lighttable.com/
