In this tutorial I will help teach you how to make a cool abstract 3d picture in Photoshop. (Like the picture below)

The first thing you need to do is open a new file in Photoshop., and set your background and for-ground colors to one of the black, and the other white. Then go to Filter>render>clouds. After you do this you should have some nice black and white clouds on your screen. Now go to Filter>Stylize>extrude and use the setting below.

Now you should have some short 3d pyramids on your picture, now we are going to raise them up a bit to make them look cooler. So do the same thing again except this time use the settings below:

 

Now you should have a picture exactly like the one below

There you go, a very easy way, to get a really cool effect.
