This is the slideshow, with screenshots instead of demos, as presented at the SBGames conference in Recife, Brazil, in November 2006.

Here's the abstract - sound interesting?  Oh, as a teaser I should add that the slideshow includes screenshots of 35 Phrogram instructions allowing the control of a 3D model with an XBox controller, running atop XNA.  Running atop XNA means it'll run on XBox 360s, when we release that support.

User-created content is arguably the hottest trend in computing today, as demonstrated by the global success and impact of Wikipedia, MySpace, YouTube and others. Games also continue to be a very important and growing business, with 100% growth in sales from 1995 to 2005, and 50% further growth projected from 2005 to 2010. Recent technology is - for the first time in decades - allowing mainstream computer users to create their own graphical and game programs. This change is setting up a coming creative revolution in gaming which will inevitably result when this statement is true: "If you can read and you can type, you can create your own computer games." This presentation will summarize the data that defines these trends and opportunities, will offer live demonstrations of KPL and Phrogram which show that this revolution has already begun, and will project near-future implications of these trends

There are many words that were presented around the slides, of course, and a Google video is available at http://video.google.com/videoplay?docid=-5465728864323068523&q=sbgames.  If you find the slideshow interesting, try listening to the audio from the Google video while reading the slideshow.  The video quality is not good, thus reading the slideshow while listening might be better.
