Download the InterKnowlogy Videos of the Surface Applications they have built so that you can run them locally without an internet connection
You can always see them with an internet connection in silverlight players at: http://silverlight.interknowlogy.com
Each zip has the streamed video file (wmv) along with the Silverlight player to run the video. you can view the video directly in Windows Media player if you want.
These videos are not professionally recorded. They are simply project update videos becuase it’s very difficult to show progress on a Surface project in technologies like LiveMeeting.
VitruView (The Surface Heart Surgery Application)
right click on the link and do “Save Target As…” and save the zip file to a location on your computer where you can extract the video and the Silverlight videoplayer.
