As promised, here's the new WebGL demo that I've been working on! I won't be posting a live version this time (watch the video to find out why), but I will be demoing it on stage at OnGameStart this September as part of my presentation.
I have several follow up posts to this one that I'll be making soon to post the source code for this demo, describe the file format (at least the bits that I was able to figure out) and talk about some of the rendering techniques used here and why I feel this is a great format for WebGL.
UPDATE: I've now got the file format notes that I kept while building this demo avaliable as a Google Doc.
UPDATE AGAIN!: Tech talk for this demo is up now.
