Interesting. On a haswell i5 with an intel 5000 series GPU it works reasonably on Chrome without any noticeable CPU or memory impact, Firefox stable works pretty well with only slightly more load, Firefox 26.0a1 dies instantly and completely.

The fact that it kills browsers for so many people so completely is a very good indication that this is in no way ready for use by anyone for anything other then "look at this shiny demo!"

Edit: Opera and Safari show nothing at all...

In Safari go to Preferences->Advanced and tick the, "Show Develop menu in menu bar" option, then select Develop->Enable WebGL.

Which is just further proof that this is in no way ready for any mainstream use.

If your (usually not technical) users have to go through two different menus just show your fancy icons you're doing it wrong.
