Do you know where one could read on <a href="http://www.maths.ox.ac.uk/node/11427" title="link">"Modular Forms, K-theory and Knots"</a>? The combination of themes sounds thrilling! 

Edit: Zagier's paper on "quantum modular forms" will be published in <a href="http://noncommutativegeometry.blogspot.com/2010/12/quanta-of-maths.html" title="link">Clay's volume</a> dedicated to Connes anniversary.
