Showcase is a Prototype extension that displays a “list of images” as a CoverFlow gallery.

And, besides the standard horizontal look, it works both vertical & diagonal.
The extension can be easily configured to display any number of images, durations of the animation can be updated & more.

Showcase requires the effects.js component of Script.aculo.us & works in all major browsers.
