The girl is Kina Grannis, she wrote and performed this song about Digg, and through viral video, she's about to sign an album contract with a big label. She really got it, it's obvious. And the song is kinda catchy.
This is a proof that training and hard work can get you acomplish anything you set your mind to! And I mean a loooooooot of hard work! Look at them, they are like a triochromatic screen, plus there's no bad infuence to your eyes.
