First you have to love the guy's name, "Roman Mars." But you also have to love his attention to design found in all places. Roman is the creator and host of the 99% Invisible podcast. In his TED Talk he not only does a wonderful presentation as if he is producing one of his podcasts, but wonderfully reveals the simple approach of design using flags. Yes, flag design. To me it is the earliest example of the icon that simply and graphically communicates about the person, place or thing it represents. The approach used in flag design principles shared in the presentation can be used in virtually all graphic design whether it be a poster, a business card or a logo.
Enjoy
