A draft standard has been released for WebGL - the graphics technology that might one day allow websites to be as flashy as the latest video games.
The Khronos Group, which oversees the OpenGL graphics technologies, has signed up a bunch of companies including Apple, Google, Mozilla and Opera, to help develop the best code for the task. The first version of that code has now been published.
Editions of Safari, Chromium, and Firefox are available that support WebGL, and if you have one of those installed then you can try various demos - there's a teapot, a particle system, and a "San Angeles" cityscape.
Over time, the functionality will be set more firmly and will roll out into the consumer editions of the various browsers. From then, you'll be able to begin using WebGL on regular websites. Microsoft, however, is not involved and has remained tight-lipped about its support for WebGL.
