What the Birds?

I was looking at the iOS app store today and I noticed that of the top 5 paid games, 2 of them are Angry Birds and 2 of them are games with icons that look very similar to Angry Birds. I think if you want to get a top selling iOS app these days, the best way is probably to create an icon for your app that has a cute chubby bird on it. That gives me a good idea for yet another project to work on when I can find some time...
