Mozilla keynote was basically about how to make the minimal contributions of many people collect efficiently into a final product.
Now at the "Pure Data" Artist's Language talk. "csound" is a programming language? I'd thought it was a library. Anyway, interesting little patch language, apparently has Python bindings of some form. Same kind of stuff you saw from Autodesk around 1997 or so, draw your mechanisms on screen with sources and sinks.
Good audio manipulation. Apparently video effects that can be applied against simple 3D worlds. Nice blends and fades and the like. Kind of a fun little application.
