I don't know how I missed it, but popular science author Michio Kaku was interviewed on Stephen Colbert's show in the summer of 2010 before his most recent book came out, Physics of the Impossible. As you can imagine, Stephen was very excited to hear some of Kaku's ideas. Best of all, Kaku promised Colbert the possibility of a Harry Potter-esque invisibility cloak! You can watch the video on Colbert's website.
