New additions to the site

It always gets busy this time of year but I wanted to mention a few additions to my site.  The first is I have updated the book section with some downloadable content.  I also added a code sample that shows how to draw circles around every touch point on an iOS screen.  This was used in the book to investigate issues with head-to-head play.  In addition, I added a podcast player for the Tech 411 Show which allows you to listen to the latest.  Hope everyone enjoys the coming holidays.  Cheers, Todd
