This application showcases four ways of using the radial menu widget. 

It simulates 3D rotation by using an elliptical track as a 3D-to-2D projection. Images used in the radial menus have the option to grow or shrink to further enhance the 3D rotation effect. The application supports touch interaction. 

The demonstration launches with a splash screen highlighting basic motion capability supported by aria graphics library. 

When running the application, the user can interface with it via capacitive single-fingered touch and swiping gestures. 

The main menu is a radial menu that features images stored as PNGs having been preprocessed at boot-time. It is also used as a navigation menu to the other three radial menus. 

The other three radial menus are used as image carousel. One shows a series of music albums arranged in an orbital track. Another is used to show representations of famous portraits, and demonstrates how the radial menu widget handles items with varying dimensions. The last radial menu is showing vertical rotation to simulate a business card rolodex. 

An information screen is used to explain the features demonstrated in this application.
