Frottage and rubbing are drawing techniques that allow interesting visual expression through simple rubbing actions revealing a texture or a pattern hidden in the background. Specifically, frottage is a drawing technique where one puts a textured surface, such as wooden planks, metal sheets, wire nets, and hemp cloth, under a sheet of paper and rubs over it with a charcoal or a colored pencil to make appear various strange images [Simpson 1989]. Frottage has been loved by many artists since it enables them to add incidental textured effects to an intentional drawing (Fig. 1(a)). With rubbing, on the other hand, one transfers a carved image by putting a sheet of paper on an object with a carved pattern and rubbing on it with a pencil, a charcoal, or a colored pencil. Putting a piece of paper over a coin and then rubbing over it with a pencil to copy the image of the coin can be regarded as a type of rubbing (Fig. 1(b)). This activity is done for visual amusement itself or for a primitive means of copying graphic information.
