Step 1: Start off with a blank 500x500 pixel document, add a new layer, and Edit > Fill it with black.  Once you have done this, add three 50-300% Zoom lens flares (Render) at 125%, so that your image resembles the one on the left.

Step 2: Go to the main menu and run Filter > Sketch > Chrome with a Detail of 6 and a Smoothness of 4.

Step 3: Set the colour to your own personal taste using Image > Adjustments > Hue/Saturation. I chose a blue (200 Hue 60 Sat).  The final colour choice is, of course, up to you, but remember to use a darkish duller colour at first, because our creation will get lighter and lighter as the tutorial proceeds.

Now Layer > Duplicate this layer and change the blending mode to Lighten.

Step 4: Layer > Duplicate this new layer and change the blending mode to Overlay.

Step 5: On the Lightened layer, run Filter > Distortion > Wave, and click on the randomize button a few times till you get a nice effect like the one opposite.

Step 6: Layer > Merge this layer with your original layer, duplicate it, then Edit > Transform > Flip Horizontal, set layer blending mode to lighten, and merge it again.

Step 7: Getting the idea yet?  If not, duplicate the original layer again, flip it vertically, set the layer blending mode to lighten and merge it.

Step 8: You can stop here or add one more duplication at a 90 degree angle. Either way, you should have a fancy and highly fashionable texture of your very own now! Enjoy!
