Text Tutorial

Before we begin make sure your height is long then your width, cause this project were going to apply the filters, and the rotate it 90 degrees and then apply the color. (I set my dimensions to 200x450)

Now make the left half black and the right half white.
Image

Now go to Filters/Distorts/Wind, and change wind to blast, and the direction from left to right.
Image

Now go to Filters/Blur/Motion Blur
Make sure the angle is at 0, and adjust the length so it's close to the edge, but not to close.
Image

Flip the image horizontally and apply the filter an additional time. You may need to repeat the process a couple times depending on the dimensions of your image.

Once you've finished bluring it, go to Image/Transform/Rotate 90 Degrees Clockwise

Then copy half of the bottom, then select half of the top, delete it, then paste your copied selection, and then flip the selection vertically.
Image

Now create a new layer, grab a rainbow gradient, and then make the gradient going down vertically on the project.
Image

Then copy half of the bottom, then select half of the top, delete it, then paste your copied selection, and then flip the selection vertically. Then Set the Layer Mode to Overlay
Image

Now create another new layer, make sure you still have your rainbow gradient selected, and then make a gradient going horizontally on your project, and then Set the Layer Mode to Color/Hue
Image

You're now done!
