Roman Mars is a very accomplished and well-regarded public radio producer based in the Bay Area. He just started the second season of his show 99% Invisible. Each episode is a beautiful, rich look at one tiny corner of our lives through the lens of design. The first episode of the season is about the periodic table. One of my favorites from the first season was about flag design. The show is free in iTunes. Roman was a scientist before he got involved in public radio, and his show combines precision, depth and aesthetics in a really lovely way.
