I like to call my study Gödel, Escher & Bach studies. I learned about the book after no less than 3 people mentioned it when I described the ESSLLI2002 conference to them (I can't remember why exactly, at the time I was mostly interested in the concept of "flow of information").
Anyway, two weeks ago, I visited the Escher museum in Den Haag, who according to the 20-minute film shown in the museum, considered Bach a "similar soul". Bach, it turns out, is having a
festival here in AmsterdamAlso, I've recently read there is a movie after the book: it's titled "VICTIM OF THE BRAIN".
