Since my gigapan doesn't fit my whitewater boat, I guess my kayaking panos will be with the iPhone app from now on, but the robot goes rafting. Thinking about a high water Middle Fork of the Salmon run at the end of the month. Don't suppose that Bing Maps Photosynth is looking for a project to sponsor?
