The web pages for ICM 2006 point to this link for live trasmission of the sessions and recordings of previous sessions. Warning: I have not tried to view anything myself yet, so I hope this works :-)
One of yesterday's highlights for my family and close environment was Richard Stanley's invited plenary talk. Stanley is the "godfather of algebraic combinatorics", or so says Doron Zeilberger on his links page, and the former supervisor of Bridget Tenner (Kári's girlfriend) , and of Einar Steingrimsson, the head of the algebraic combinatorics research group at Reykjavik University.
For those of you who would like to read it, Stanley's paper for ICM 2006 is Increasing and decreasing subsequences and their variants (34 pages).
