The static background paper or canvas texture usually used for Non-Photorealistic animation greatly impedes the sensation of motion and results in a disturbing ``shower door'' effect. We present a method to animate the background canvas for Non-Photorealistic Rendering animations and walkthroughs, which greatly improves the sensation of motion and 3D ``immersion''. The complex motion field induced by the 3D displacement is matched using purely 2D transformations. The motion field of forward translations is approximated using a 2D zoom in the texture, and the camera rotations is approximated using 2D translations and rotations. A rolling-ball metaphor is introduced to match the instantaneous 3D motion with a 2D transformation. An infinite zoom in the texture is made possible by using a paper model based on multifrequency solid turbulence. Our results indicate a dramatic improvement over a static background.
