Why do you find it amazing? I saw this first probably 10 years ago with java applets. Is it more amazing because applets are unfashionable?

No, it's because Applets, like Flash, are a narrow, specific, proprietary setting. Nobody has ever questioned that Java can handle something like that.

The interesting part here is that it is showing that browsers and JavaScript, with a very different approach than Flash or Java, can now handle this sort of computationally intensive, graphics intensive application without any OS-specific plugins.

> computationally intensive, graphics intensive application

Wake me up when that means something from only 5 years ago and not 20.

I suspect a pure Javascript Gameboy Advance emulator is not too far off :P

getting code to work is easy, getting the largest most influential tech companies to cooperate on building a platform for you to deliver applications that work on most devices in the world entirely for free with no real financial incentive.

thats a plain miracle.

applets don't work on [insert random browser on device]

yeah, but as people have noted this doesn't work on anything other than the latest builds of chrome and safari. Still impressive but this is not exactly a compatibility win.

But this is an implementation based on open web standards. It'll eventually work on mainstream Firefox, Safari, Chrome, Opera and maybe (if <canvas> is supported and planets align) IE9.
