iPOP Express START-button Demonstration 1
 
Click the button to launch the demo (if not already launched).
 

 
Some of the points demonstrated here:

Panel depth - you can open up some sub-menus to a depth of 10 panels if you follow the arrows.

Custom colours and text sizes: small text has been selected, and a custom set of colours (more suitable for a webpage with a black background).

You can also see the radically different panel shapes this menu can create - it adapts itself automatically to the height and width required by the text.
