Start off by using your text tool to write your title, and using the Font menu to customize your size and style.

Right click on your text, and choose "Create Outlines"

We are going to add a gradient to your text. Open up your gradient window, and use the settings below. Choose "linear" from the dropdown menu, type in 90 degrees for your angle, and click on the color icons on each side of your gradient preview to change the gradient color to a light blue - dark blue progression.

Click on the Pen tool, and change the color mode to"none"

Use the pen to make a selection similar to mine.

Use shift to selection both the text and the new pen path. Bring up your pathfinder menu and click on the divide icon. This will break up your gradient into two parts.

Right click on your text, and choose "ungroup."

Now, while holding shift, selection just the upper portion of each letter of your title, giving you a selection similar to mine.

Lets group these pieces back together by clicking on the "merge" icon in your pathfinder window.

Copy your selection by press Ctrl+C and then Paste it by Pressing Ctrl+V. Change the gradient to a black and white linear gradient as shown below, and position your copied selection in line with the text below it.

Bring up your transparency window, and change the layer mode to "screen."

Your done, you should have something similar to mine!
