I get a dialog box : "There's no WebGL context available.". :\

Using Google Chrome 19.something on Ubuntu, with open source radeon driver.

Chrome 18, nVidia GTX260M, on Windows with official binaries.

Same error.

Chrome blacklists most opengl drivers on linux (except the proprietary nvidia one) since old mesa based drivers don't work too well with webgl. You can change this in about:flags, "override software rendering list" (and restart)

I got the same box on Safari OS X. Then found 'Enable WebGL' on the 'Develop' menu.
