Core Image is the new technology in Mac OS X that heavily leverages Quartz Compositor and the machine's GPU. Demonstrated at WWDC in 2004, it provides access to the most common Graphics API's. It provides the ability to edit images on the fly (which used to be handled by Quartz/Quartz Extreme) and apply dazzling effects to them. It can also apply 3D transformations as aptly as 2D transformations.
