Have you tried Photosynth? If you haven’t you might want to take a look. It’s a web application that stitches together digital photos in 3-D and then allows you to navigate them in 3-D. It’s the coolest technology I’ve seen from Microsoft in a long time. Unfortunately, it only works with Windows so far.
I just uploaded a synth of Orr’s exhibit, A Bridge to Japan, at the Morris Graves Museum just to try it out. There aren’t quite enough photos for them to all mesh completely but you can still see all of them if you change to grid view.
Take a look and let us know what you think!
