The iTunes Expanding Album Effect in HTML/CSS/JS

The text and background colors are generated from the album artwork (like in yesterday's Panic post) using a modified version of the Color Thief library. More info about the demo here: http://thomaspark.me/2012/12/the-itunes-expanding-album-effe...

Really cool animation. It seems like this could be done in pure HTML/CSS if you used the checkbox (radio button would probably work better) or (possibly) focus hacks.
