Though that fan does kick up quite a bit...
Color me unconvinced, but we're looking at graphics that are roughly on par with what we saw desktops games in 1999: http://www.youtube.com/watch?v=3R2nCrsDHeA
I realize that this is just a small tech demo, but even still -- GL is only part of the equation. The kind of platform optimizations that are eeked out in the game industry are substantial and extend well beyond just the GPU.
The interest in web (flash) games was largely driven by the difficulty of distributing casual native games -- and that's quickly becoming a solved problem.
1. I don't have to install it. This means I can satisfy my desire for instant gratification and quickly go back and upvote it.
2. I support open standards. I'll upvote it just for the fact that it's implemented in WebGL and not some proprietary bullshit, and I'll continue to do this until all the proprietary bullshit is long dead and gone.
Longevity: x86 is in no danger of disappearing, and even if it was, popular open-source x86 emulators and virtual machines exist, with better performance and compatibility than a lot of WebGL implementations.
Proprietary platform: x86 has a very long history and is approximately perfectly documented. On the other hand, every browser implements WebGL slightly differently.
Can't see the source: Javascript can be minified and obfuscated to the point of incoherence. On the x86 side, i feel that this would be better addressed by improving assembly education: Everything is open source if you have a disassembler.
Software Freedoms: It's inherently more free, in the RMS sense, to have the content locally on your own computer than it is to stream it from somewhere else.
If, on the other hand, the intent is to prove that I suck at video games, then it's a resounding success.

The display jiggles a little bit. About twice a second the camera shakes a little—I think maybe the roll of the camera changes?
I'd like the option to invert the up / down keyboard buttons—I kept going up when I meant to go down, and vice versa.
Pretty impressive, though. Now, if Adobe could produce a webgl to flash 11 converter, it might be possible to actually do something like this commercially.
