Today in Youtube... oh, I'll just quote Nick:
An short introduction to interactive fiction (text adventures, such as Adventure and Infocom's games), the history of the form, how they are played, and a little about what's involved in writing them. With Nick Montfort, http://nickm.com Video by Talieh Rohani for the 2009 Jornada Nacional de Literatura in Passo Fundo, Brazil.
Nothing you or I don't know, but good for the general audience. Plus, you can see some of Nick's hardware collection.
