This tutorial explains te method I used to create the "Human Thoughts" wallpaper on Deviantart... It is really simple and provides stunning effects.
Step 1: Open any Previous image (Probably with mild colours e.g. Scenery, Grass etc)
Step 2: Filter --> Stylize --> Wind (Wind, From the Right/Left)
Step 3: Press Ctrl+F to repeat... Press again if you want
Step 4: Filter --> Distort --> Polar Coordinates (Rectangular to Polar)
Step 5: Filter --> Stylize --> Wind (Wind, From the Left/Right)
Step 6: Press Ctrl+F to repeat... Press again if you want
Step 7: Filter --> Distort --> Polar Coordinates (Rectangular to Polar)
Step 8: Filter --> Stylize --> Wind (Wind, From the Right/Left)
Step 9: Press Ctrl+F to repeat... Press again if you want
Step 10: Filter --> Distort --> Polar Coordinates (Polar to Rectangular)
Step 11: Press Ctrl+F (Once only!)
Now you should have a nice image... Press Ctrl+U to open up "Hue/Saturation" and change the hue to get nice effects. You can also press Ctrl+I to invert the image to get more effects.
Also experiment with the number of times you do the polar Coordinates to three or more, but remember to restore the image by using the same filter but in reverse i.e. Polar to Rectangular the exact same number of times you did the first.
