On November 2, 2012 Walt Disney Animation Studio’s "Wreck It Ralph" will arrive in theatres; preceding the feature film will be the black-and-white short "Paperman". For the first time in animation history, "Paperman" uses a combination of computer-generated and hand-drawn animation techniques to bring the story to life with first-time director John Kahrs at the helm of this bold endeavor. Disney has released first look images for Paperman and they look beautiful, in all of their black-and-white nostalgic gloriousness mingled with modern and classic technologies.
To clarify the confusion over what makes "Paperman" groundbreaking, here is a little more information. Director John Kahrs led a team of 2D and CG artists using a proprietary program called Meander that employs a technique called final line advection. The result is the ability of the artists to add a level of grace and expressiveness never before seen in an animated picture.
Hope that helps clear things up!
