D-branes are considered by the general particle physics community as the arcane inventions of the initiated having no relevance to even semi-realistic QFTs. In this seminar I want to provide compelling evidence that the domain walls of the simplest supersymmetric extension of QCD are D-branes for the confining string of the theory. Conventional D-brane technology then leads to a very intriguing result for the forces between the domain walls which suggests some underlying but unknown magic is at work.
