Of particular interest to some of the hackers here will be the "Impact Graph." This was my first Canvas + JavaScript graph implementation and I must say that it's a pretty nice system to work with. While Canvas is strictly a painting tool, I'm considering writing a library on top of it that will give me some of the interactivity and animation tools that I miss from Flash. Canvas is positioned to seriously compete with Flash, I'd love to see more people using it.
I thought Processing.js was just one such framework to work on top of Canvas.
Does their blog have rss? I can't seem to find the feed link.
It'd be nice if the graphs did more than just master. In particular, rubinius has a lot of activity going on in the 'cpp' branch and none of it is visualized anywhere that I can find.
I was half expecting to see a cartoon emo guy before I clicked the link.
