Today we are going to make cool abstract wallpaper. In this one I'm going to use Standard Photoshop features and maybe a little bit of custom hand painting.

So let's begin. Create a document with 1024x768 resolutions and a layer.

Now let us play with gradients (on a new layer).

Overall layer options,
   
I've filled the area with this gradient several times (4 times exactly). Maybe need to change a little bit of the opacity.

Yea, this is the color I like.
Now make a copy of our key layer and apply several filters on it.
