As has been spoken about endlessly (OStatic, OSnews), there is a great blog post from 0x1fff with many (started at 35, is now many more) open source projects from Google. In fact and indeed, there is some cool stuff on there. I knew about Caja and Protocol Buffers (wish there was a JS port of protocol buffers) but did not know about CRUSH and skia. Honestly, there are plenty of cool projects out there and my already-positive opinion of Google is only bolstered by the fact that they give back so willingly. Gotta love it.
