The Stanford Human-Computer Interaction seminar (free to watch!) is one of my regular Internet stops. I haven't watched the whole talk yet (you might have to click back and forth on the Lectures and Course Topics tabs until you can access all the lectures), but Lecture 3 for this quarter (15 April 2011) is about magic. I was impressed by the speaker's baccalaureate degree in magic from Hampshire :)
The relationship between magic and interface design has been explored before, in fact I've talked about Tog's classic "Magic and Software Design" CHI conference paper before.
