Open a new document and set the foreground color to 400045 or 660000. Select the Linear Gradient Tool and draw a line from the top left to the bottom right of the image. Create a new layer.

In the Optional-But-Looks-Cool department, utilize the Polygonal Lasso Tool and draw a rectangular selection as shown. It is easier to increase the size of the document window to draw the selection properly as you'll be drawing outside the initial boundaries of the image.

With the new layer active, utilize the Linear Gradient Tool once again and draw a selection from the middle left of the new layer downwards and to the right.

Create and position your text; in this case, we are going to use our favorite pony car. Experiment! Go to the Layers Palette and utilize the following settings.

Inner Glow: Blend Mode > Multiply, Color > #990000, Opacity > 75%.

Bevel & Emboss: Style > Emboss, Technique > Chisel Hard, Gloss Contour > Ring.

Click on the diagonal line to make a point and drag it down to the area shown. You can experiment by creating various points to create a myriad of final results.
