I wonder why they came up with a new library instead of contributing to box2d directly? Unless they had to break box2d's API (but off the top of my head, without looking at the code, it's hard to see why they would have to)

What's wrong with creating something new? If someone decides to attempt something but there's already a similar project, why do so many think they should abandon their own to contribute to the other? They can always contribute down the road.

It's surprisingly reasonable that they did not use Python or JS for it. I wonder how they came up with this project though - do they want to boost Android/NaCl games?

Earlier quoted context omitted.

Yep, those kind of 2d metaballs are indeed doable in GLSL - I have a WebGL proof-of-concept lying around. I really struggled to get good performance, though my shader-fu isn't up to much.

Metaballs are too expensive for more than a few particles. There are probably some other algorithms that would work better, or not doing metaballs strictly.
