Roman Mars does a live podcast about flag design at TED

Roman Mars' 99% Invisible podcast is one of my favorite podcasts on the internet. It's about all of the seemingly invisible forces shaping our understanding of the world and dictating how things operate and work with each other day to day.

Hearing him almost every week has gotten me pretty used to his format, but seeing him do it live is pretty cool too. Here is is giving a TED talk about flag design to a live audience in the same format of his podcasts. It's amazing how he is able to run everything off of an iPad. Is the app custom made or is there some sort of app for podcasts that you can load soundbites into?
