Colorbox demonstration all the same?

On http://colorpowered.com/colorbox/ there is a View Demonstration box on the left. But when I click on any of the examples 1-5 it looks the same.

All of them have Elastic Transition, Fade Transition, 开发者_如何学编程etc.

What is the difference between them?

The different demos illustrate 5 different colorbox styles (UIs). All of the galleries are the same amongst the five. Download the plugin and see the five different folders.
