From the Chapter Description: Here is a new term, coined to describe a new and fascinating class of mosaic patterns. Each shadow mosaic design consists of a black motif upside down, interlocking with and alternating with the same motif in white, right side up. These contrasting patterns interlock with each other in a multitude of interesting ways, and lend themselves to several different interpretations, which can be varied at the knitter’s whim. Whichever method of interpretation you choose, your shadow mosaic designs will look the same upside down and right side up, and will “shadow” each other in clever and intriguing shapes.
