Here's a starter template with the 5 gate screens featured in this Rapid E-Learning Blog post. Feel free to use them as you wish.

You can see the gates used in this demo. In PowerPoint, you'll have to create a lightbox type slide that you link to and from there add the gate objects. All you need to do is copy and paste it onto the slide. Then be sure to set your hyperlinks to the appropriate slides.
