If anyone ever wonders why it's important not to "standardize" on any one program, innovations like these are a good example.

Continued kudos to the little guys (Opera, Mozilla, Apple) for actually doing something useful with the browser. And Microsoft, I'm tired of hearing the word "innovation" from you.

There's also O3D. Hopefully one of the two quickly becomes the clear standard.

O3D is supposed to be more efficient but WebGL is more familiar to programmers, has more browser vendors behind it, and has official backing from Khronos.

The two aren't mutually exclusive. WebGL is an immediate mode API and O3D is a retained one.
