180 degree photosynth
Micosoft runs that nice Photosynth site, with quite advanced imaging features. Now there is an iPhone app that allows to create Photosynths on the device itself in a quite easy way: take a picture, and another one that somewhat overlaps the first, and repeat that a few times. Then you end up with a Photosynth that can be uploaded to their site. Embedded below is a 180 degree shot of our garden.
