Here is a link to yet another fantastic source of Custom shapes: http://www.deviantart.com/?q=Photoshop+Custom+shapes&offset=30
Here is a quick rundown of how its done.
Find a shape that you like and create it using the same technique I described in the previous tutorial.
Make it the color you desire.

Next, find the shape you would like to use for the inner effect.
On a new layer, create the shape inside the outer shape. It does not matter what color it is as we are only using it as a template.
name the layer inner template and turn the layer off.

Choose your Gradient Tool, select the foreground to transparent preset from the gradient editor.

Create a linear gradient going from top to bottom on the upper half of the selected area.

Then hit Shift + Command/Control + I to invert the selection.
You should now have a set of marching ants on the edge of the canvas as well as the original selection.

Lower the opacity to about 60%. Your done.
