I remember seeing this several years ago, and was thoroughly impressed. The gentleman who wrote this library used it in an interactive essay called "Ladder of Abstraction." [1]

Here is its previous HN discussion: [2]

The gentleman who wrote it is Bret Victor. I highly recommend this talk [1] by him (500k views), he's a true visionary.

Also consider reading his seminal essay called "Magic Ink" [1] and afterwards take a look at the publication date and try to remember where the web was back then.

I have watched this video a few times and periodically revisit it. Sometimes we get to far into the woods and need to be reminded where we can go writing software.

Just watched that talk... amazing. Do any of the tools that he uses in that talk exist?

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/

I thought this was a few years old as well but I'm happy to be reminded of it.

I really enjoyed this http://worrydream.com/#!/ExplorableExplanations
