I also have to make 360 degrees panoramics of the sites. I found a great program for PC that joins the pictures into a big scene, it's at www.pixaround.com.
Wouldn't it be nice if I could see those panoramics in the newton? Well, I'm lucky. Today I found a piece of code from the amazing Lee Moon that does just that, show a picture as a 360 degrees panoramic, with source code! it's at Marco Mailand web page.
