Yes you are reading that right. Angry Birds, the super-famous game on Android, iPhone and tablets alike, is now playable on a desktop web browser. Probably not all web browsers but it runs on Chrome and Firefox. Supposedly it is only for chrome, as that little logo at the tail end of the Birds, implies. However I was able to run it smoothly on Firefox versions 4.0 and 4.0.1. My brother, also played with it on Firefox 3.6.x version.
Right now the game only has 2 levels. Poached Eggs, an old one as many long-time Angry Birds players already know, and Chrome Dimension. The latter is new and was obviously intended for this release.
The game was developed using HTML 5 although the audio is embedded in Flash.
Below is a screenshot of Angry Birds on Firefox 4.0 running on Ubuntu Natty Narwhal. Earlier I was running it on Firefox 4.0.1 on Ubuntu Maverick Meerkat.
Where to play it? Point your Firefox or Chrome browser to: http://chrome.angrybirds.com/
