This effect was generated in Filter Forge, a Photoshop plugin that allows you to create your own filters.
Makes fragments of your image float on a sphere or a plane.
If your image is landscape oriented (width > height), make sure you check "Landscape Oriented", and if its portrait oriented (width < height), uncheck it. With square images this setting doesn't matter.
Note that some settings of the plane-mode might not yield tileable results.
Ignore the controls named with underscores - they are there to link random seeds of certain internals.
Thanks to ubersev for his proportional gradient solution.
