A photo of a spray-painted metal grill served as the source image for this example of a Kaleider Grinder Surface.  A Cone Funnel was rendered with the Base Cone adjusted to produce 12 Cones.  The Replicate Base Cone option was not set, causing each of the 12 Cones to be rendered from its own portion of the source image.
