I like the 3D immersive experience, but I have found that I also really like the unfolded image that results when one saves the panorama to one's photo album, because of the interesting warping of the image. The problem of unwrapping a sphere onto a plane has been studied, notably in mapmaking, when a map of the spherical earth needs to be constructed. However, there are many other projections that give rise to interesting-looking maps that are created by different unfolding techniques. For instance, the Peirce Quincuncial map is one of my favorites. Perhaps, there could be an option for various interesting projections. Also, a method allowing one to choose where the left/right bounds of the projection fall in the image would be useful, because often one takes a full panorama, but discovers that the edges of the image cut right through the most important part of the image. It might be interesting to allow vertical translations as well.
