RapidWeaver Stacks add-on info:
Animated background color and animated text color. You're the Tivoli Boss, you get to pick the colors. Use the Tivoli Stack to catch attention to text, images, videos. The disco example below (example 1) is – maybe – a little too disco! Or is it?

Combining more Tivoli Stacks you can add a strobe light effect. Wrap it around an image or video to create an animated frame (example 3).

Example 5: Turn off animation (settings) > add a background imaged > drop an image on top of the background image > set image opacity to 0.0 on hover (settings) and you got a nice looking image replacement rollover effect.
