I must say that this site/music video is one of the most beautiful things I've ever seen on the web. The song is called “Soy Tu Aire” which means "I'm Your Air" by Labuat.
What a stunning use of interactivity and music... Many props to Labuat and Sony for being so creative. Anyways, you MUST click and play the song through to the end.
A million thanks to the forever rad miss Kati for sending me this link. You truly made my Thursday :)
