It started with some
beautiful pictures by Russian artist Alexandre Duret-Lutz and moved on to a discussion:
how was this done? Well, the following technique might not be exactly the same one, but at least it’s really quick and rather hilarious.
Landscape
Find a good landscape. Preferrably a large image without too much going on in the sky as the sky will become a bit distorted.
In this case, I had the tree in separate layer, so I cut that out. The sky is going to be stretched quite a bit, so let’s be clean.
Squarify
If you want a round globe-like end-result picture, your canvas has to be a perfect square. I expanded the canvas (Image - Canvas Size...) so the width and height were the same. I filled the new room with sky blue. It doesn’t matter so much, as the topmost part of the sky will end up so distorted that we’ll crop it away.
Flip It
The filter we’re about to use is pretty old, so you’ll have to do most of the work outside of the filter. So flip it vertically.
Polarize!
Now it’s filter time: run the Filters - Distort - Polar Coordinates... filter.
It’ll look like this.
Stitch
Zoom all the way in, and using the Clone Stamp tool, diligently paint over the vertical seam that goes from the middle, all the way up to the top of our sphere. The Clone Stamp (keyboard shortcut S) is used by holding ALT, then clicking a spot nearby where you want to smooth over things. Once you’ve selected a “clone source” you can paint normally and it’ll clone the spot you selected.
I added back the tree I removed early on, for maximum fun.

Voilá. Surreal Mario Galaxy.
These tutorial pictures are also available in my photostream. Non-spherical prints are also for sale, actually, so feel free to purchase a cowscape for your kids room.
[Update]: My colleague at the office points out to me that the Polar Coordinates filter is very useful for 3D texture artists in creating “spheremaps”. Not coincidentally, the chap whose intelligence is above average, has built his own 3D engine for visualizing architecture; here’s a quick-preview of a spheremap on a teapot:
