1. Go File > New and make a 400x400 image. Press (D) on your keyboard. Then click on the gradiant tool. Put the settings on the top to this:



2. Now, just start going crazy on the blank canvas. Don't overdo it though, but the crazier it is the crazier your final result.



3. Now for some fun. Duplicate your layer ( Layer > Duplicate ) and then go to filter > Distort > Wave. Put the settings to this:



4. Now change the layer style to Lighten and you should get something like this:





5. Do this about 3 or 4 times. Each time you do the wave, make sure you hit the 'Randomize' button with those settings, so you will get a nice new wave. You can also experiment with other layer styles, but for now I will only use lighten.You can also flip the layer a few times when you are doing different layers for different views. ( Edit > Transform > Flip Horizontal/Vertical ) Don't make too many layers, or the image will become overly cluttered.



6.Now merge them all into one layer. ( Layer > Flatten Image ) (Keyboard: ctrl + shift + E)



7. The rest of this tutorial is completely optional, but could yield good results. Duplicate the layer again. Do the wave, just as you did before. Now you can play with the layer styles, that could make some interesting results.



And so on.You could crop the image and make a nice forum signature with it, add your name, maybe a border, etc ;D

You can do some colorizing (Color Balance & Hue/Saturation) to make it more interesting

P.S - Please keep in mind that this is not my original tutorial, im just remake them with my word a bit & the image aswell. Credit to the Art Maker
