Even though Tiny Wings recently elbowed Angry Birds out of their top slot on the App Store sales and grossing charts, it’s crazy thinking how huge Angry Birds is, and how the game’s popularity is growing at an alarming rate. Hell, I was doing some shopping to prepare for GDC and noticed an entire Angry Birds line of shirts being sold at Hot Topic. Today? They’re all sold out. Regardless of how you feel about the actual Angry Birds game, it is pretty awesome to have something like it that is bringing smartphone gaming to such a massive mainstream audience.

I’m not sure this is going to get me to start using Bing over Google, but I’d be lying if I said I didn’t love the various animated shorts that Rovio has released of the Angry Birds pigs and birds.
