Computational Public Space

I am always fascinated by the kind of tech that Bret Victor works on. While I can grasp a lot of the things and how to apply them from his previous work (like 'Stop Drawing Dead Fish' etc) this newest stuff is beyond my understanding.

I would love to know more about how this whole system works and why it is so much easier to work with. Code and computation is generally so reliant on the specifics and the details, so this approach seems to be touching on something that has a fundamentally different design, and it is just really fascinating.

Why is something this interesting and full of good ideas invisible on HN? The idea of computation around us, like street lights, has so much promise.
