A TON of people play this Angry Birds app.  I haven't played it, but I see a bunch of videos on YouTube about it...heck there are even achievements videos for the game up there.  It's gotten so popular, a gaming group make this movie trailer for what they think the movie would be like if Michael Bay got involved.

Check it out.  I really like the RoosterTeeth videos.  I've been watching RedVsBlue since the first season, almost 9 years ago.

Oh, and if you play Angry Birds...enjoy the game and trailer!
