There are two constants about the world wide web. One is that “Information wants to be free”. And the other is that if you ask nicely someone out there that is into the same things you are knows where to find that very stuff you are interested in on the net. As proof of this concept I offer this link from Commenter John Swords who found a MP3 of the Keynote of Ray Kurzweil from the GDC held last month. Big thanks for the link sir.
