WebGL Report is an open source project that checks whether or not a browser supports WebGL, and if so, reports details such as supported extensions and implementation specific capabilities.
Travis Glines released a proof of concept chat app using WebGL, Node.js, Websockets and a few other technologies. Its a fun and interesting way to demonstrate a chat room in real time. "When you think of 3D on the web, you typically think of games first. Games in 3D are fun, but what if you could do multiplayer gaming inside a web browser, with a server that could scale?" wrote Travis. This demo reminds me a bit if BZFlag in its early days, and is worth a few minutes of your time to check out.
Open Source Project for Animated COLLADA models in XNA 4 aims to be an alternative to the built-in XNA Model class that is able to load animated 3D models from XML based COLLADA files.
