Well, I've been on the fence for a while, but I'm fairly sure that I'm not going to build native code demos anymore. WebGL just enables far too much awesome stuff. This demo on its own was impressive, but the fact that people are able to design new parts of the demo is what sets it apart.

With WebGL, it becomes simple to build an online, collaborative demotool where group members can easily work together on building new productions. That's simply unprecedented and may lead to a rebirth of the demoscene.
