The popular (and very addictive, trust me) game that started on iPhone ($0.99), was ported to Android (free), and is now available on the App Store for Mac (i bought it but i dont remember the price), is now available to play for free online.
It works on the latest version of Chrome and Firefox 4. I've tested it to work in IE9 too.
Try it out now!

Let's see, I use Angry Birds on the following platforms:
-Mac
-iPhone
-Android
-And now this
I love the game and I've beaten the game at least twice, but since I have a habit of getting different phones (I havan't lost my new one yet though), I am constantly replaying it.
Anyway, give it a shot!
