so this tutorial will teach you how to make this
there are 32 steps, which is about 22 more than intended
you will need
tilinghttp://paintdotnet.forumer.com/viewtopic.php?f=16&t=22521
polar to rect http://paintdotnet.forumer.com/viewtopic.php?f=16&t=4173
first create your picture, the same size as your display
then select the circular gradient with whatever color you want
then make one in a corner going 1/2 the width of the image
duplicate that layer and flip it horizontally
duplicate the flipped one and flip it vertically, then duplicate that one and flip it horizontally
hit f4 and do negation blending on all of them
will end up like this
flatten it
invert the colors
cut half of it away with the rectangle select
and put it in a new layer
flip it horizontally and do negation blending
and voila
then go to relief and do it at 0, 90, 180, and -90
you should have this
then duplicate it and flip it
set layers to multiply
flatten it
then create a new layer and put a small circular gradient in the center
blend it with negation (i believe, forgot to take a pic)
invert the colors
then do the relief thing again at 0,90,180, and -90
use tile image with the settings shown in the picture
then polar to rect, with settings shown
and polar inversion with these settings
cut away half and put it on a new layer
flip vertically and overlay
flatten it, cut away half, put it on a new layer, flip the new layer vertically, and flatten
render clouds with these settings (also use gaussian blur a bit if you want to, like 1-3 at most)
polar to rect with these settings
polar inversion with these settings
and you are done
