From an end user's perspective, this demo is a monstrosity (like pretty much all WebGL stuff I've ran across so far). I opened the link in a background tab, then my system started thrashing and Firefox got stuck. Restarted Firefox only to have it reload the tabs and freeze again. Had it running in the end and got to see the 3D butterflies flying around in a choppy music video.
It's quite CPU-intensive, but well worth watching if you can get it to work. I had to watch it in Chrome and bump my screen resolution down to 1024*768 to watch it smoothly. It was well worth it.
I don't think that having to bump your screen resolution to get a website/video working is anywhere close to reasonable. The point was to replace Flash for web multimedia because it was too resource intensive and unstable. What we see now is a half-supported proof of concept growing out of unrelated technologies.
This might be the beginning of something great, but WebGL still has miles to go before being viable mass consumption technology and it's important to recognize that.
Thanks, I'll go look for the disable button now.
