WebGL is disabled by default in the latest Chrome Beta (9.0.597.45). To get WebGL in Chrome, you need to either:
1) Run the Chrome Beta with the ''--enable-webgl' flag from the command line:
Chrome Beta can be downloaded here: http://www.google.com/landing/chrome/beta/
2) Run the Chromium nightly build
Instructions for getting Chromium here: http://khronos.org/webgl/wiki/Getting_a ... 2FChromium (Make sure to get the Chromium nightly build, not the Chrome Beta.)
Just running the Chrome Beta is not enough for the time being.
Hopefully this will get fixed soon.
