What do you see?
I stumbled upon this workflow a while back while learning how to do mini-worlds. I just leave off the last part, which is the polar conversion step at the end. Here's how it goes:
I take a landscape image that has a prominent feature on either the left or right edge, like this base shot which has a set of hills rising up toward the right edge. I do a pretty extreme pano crop, then add canvas on the right so that I can flip the image and place the mirror image into the right half. Now I have one very wide pano image. I go to image>image size and make the image square. Since I'm working on a tiff file at this point and have resolution to spare, I want to add pixels and not take them away, so I make the vertical pixels equal to the horizontal pixels (stretching the image vertically instead of squashing it horizontally). Now there is a square image that has this strange warping effect, and you can crop it to whatever aspect you like or makes sense for the image.
This is a four-image HDR converted in HDR Efex Pro. Then I used Topaz Adjust and Detail and did some color adjustments in CS5.
