Opera's WebGL Tech Demo: Odin
Opera has created an impressive WebGL demo called Odin which they describe as:
Odin is a demo created to showcase what you can do with WebGL and hopefully inspire people to create great content for the web. It uses collada as a source format and aims to be able to read both COLLADA directly as well as a run-time format created from COLLADA suitable for releases.
The Code for Odin is on Github and the demo can can be viewed by clicking on the image below (warning: it’s pretty processor intensive)
