Radian is a simple radial application launcher. The interface is triggered by a continuous right-click and is divided into four slices. Each slice can be configured differently, currently supporting the following modes: 

Custom - the slice will contain shortcuts manually dragged from existing shortcuts or files (from the Quick-Launch, Desktop, Start-Menu, Folder, etc...)

Quick Launch - shortcuts from Windows' Quick-Launch

Desktop - shortcut from Windows' Desktop

Recent Docs - recently opened documents

The right-click trigger resembles the right-click mechanism on many hand-held devices, allowing you to access the menu quickly without needing to scroll to a certain area on your screen. The menu can be loaded by right-clicking and holding anywhere on the screen. A special effort was made to make sure this feature doesn't get in the way of normal right-click usage.
