I wrote this tutorial when I made this:
I did some things to it that aren't covered in this tutorial, because I forgot them. You'll need to play around with this to get what I got.
Firstly, create new, 438 x 400
Next, goto Filter>Render>Clouds repeat
Repeat until you get it nice and even, you should get something like this:
Now goto Filter>Artistic>Plastic wrap
Use these settings:
It should look like this:
Now duplicate the layer, in the layer palette/window:
Duplicate the layer twice, then
Set the blending mode to 'lighten', on all layers
Select the top layer then go:
With these settings
Now select the layer below the top layer, do the same thing, but use these settings
It should look like this now:
Now do this:
Then, go to Filter>Distort>Wave, use the default settings:
Repeat, but click randomize a few times
It should be looking a bit like this:
Now go:
Again, then
Use these settings:
It should look a bit like this:
Now go:
With these settings
Now go
With settings on 75%, mode 'overlay'
Your final product should look something like that.
If it looks too unorganized for you, then do a bit of blurring at step 3.
This is what I got:
