This page shows 5 different stacks:
1. BACKGROUND STRETCHER STACK: Create a striking home page or splash page using an oversized static image or add a dramatic slideshow to cover your whole background. The Background Stretcher is jQuery-based and will dynamically resize the images according to the size of the browser window.
Here I've used only one image but you can add more photos and make a background slideshow with this stack.

I've added some extra CSS in the Custom CSS (see the Manual) to make the container and pageHeader transparant and to hide the image, shadows, etc.
This RapidWeaver topic explains another method for adding a full page background image.

2. The FONT RESIZER STACK
3. The SLIDEY NOTE STACK (below right).
4. The SlideMP35 STACK... well you cannot see it actually but you hear the music!
By default it sits at the bottom of this page, but I've hidden it and the music starts automatically. Great for those who like background music!
5. The build-in 3-Columns stack.

Below is the Font Resizer Stack. No explanations needed, I think. Try it.
This is the Slidey Note stack. A simple to use stack that allows your web visitors, when scrolling through content on your web page, to receive a slide-out dialog box.
Great for highlighting content , or just adding special content for advertising or promotional material .
