Convergence is the part of Stardock's Object Desktop that ties all the programs together.
It allows users to create true "skins suites" called Skin packs. A skin pack is a collection of icons, skins, and themes put together into a single file. When applied, Convergence communicates with your installed programs and directs them to change their various skins to the ones in the skin pack.
So a user wanting to have a particular overall look to Windows would simply apply a single Convergence skin pack instead of having to go to WinAmp, ICQPlus, WindowBlinds, DesktopX, ObjectBar, IconPackager, CursorEx, NeXTStart, etc. and manually load the appropriate files.
In short, Convergence combes the strength of your installed skinnable software into a single super theme.
It is currently only available on Stardock's Object Desktop (www.objectdesktop.com).
