His "interactive exploration of a dynamical system" looks like some very sweet software.
It's not an entirely new concept though. Modeling tools like Vensim and Stella do something very similar, modeling differential equations with "stock and flow" diagrams. Modeling problems with tools like these is a pretty active field, with applications in economics, ecology, and engineering. There are a fair number of books about it.
Vensim has a free "personal" version, if anyone wants to play around with this stuff. It's definitely not as elegant as Bret Victor's demo, but might be better for more complicated systems (depending of course on how much Bret left out of the demo).
