Serial App Idea

I have become completely riveted by the new podcast called Serial (www.serialpodcast.org), so much so that I spent all weekend designing a better app experience to listen to it. I started by redesigning the Serial logo (which was already good, I just simplified it a bit) and that led me to this app and this new kind of audio player. Then I couldn't help myself and designed a totally new logo for WBEZ Chicago (seen here at the bottom).
