I recently discovered that it is relatively easy to create photo spheres similar to what you see on Google Maps. This is using the Street View app for iPhones. Unfortunately, while they are really neat, they are not easy at all to share. The app makes your only option for sharing emailing a flat version or publishing to google maps. That very much limits what can be done with them. Right now it is not even easy to embed one of them into this blog!
Still, it is easy to create photo spheres of outdoor areas so I will probably make more while hiking. Here is one I took in Nashville.
