Start a new document about 800x300.

Reset your foreground and background color to black and white (Press "D").

Then go to Filter » Render » Clouds.

Select the type tool and create your text. Make it fairly large, and position it towards the top.

CTRL+CLICK the text layer to load the selection, then go to SELECT » Feather, and enter 3. Now hide the text layer.

Set your foreground color to white and background to light grey. I used:#7E7E7E.
Now create a new layer, then go to Filter » Render » Cloud. Then go to Layer » Image » Flatten Image. (if prompt for "Discard Hidden Layers" Click ok.)

Now go to Image » Rotate Canvas » 90CW. Then Filter » Stylize » Wind:
Method: Wind. Direction: From the Right. Press CTRL+F about 7 times to reapply the wind filter. Then Image » Rotate Canvas » 90CCW to turn the image back to normal viewing.

Now Filter » Sharpen » Unsharp Mask. Amount: 500%. Radius: 2. Threshold: 0.
Then Filter » Sharpen » Sharpen. Reapply twice..

Now open the color balance box and play with the color sliders to get some nice colors.

HERE'S MINE.
