The phenomenon was easily reproduced by rubbing a very dirty car hood with a dry paper towel. Figure 1 shows the results. The hand that holds the towel must not rotate, and its overall trajectory must be a circular arc of ~90deg with radius < 30cm. The resulting scratch patterns were observed under sunlight. Images of handprints were clearly being reconstructed, with the images appearing deep within the painted hood rather than upon its surface. The depth of each image was somehow proportional to the radius of the curved scratches and to the angle of illumination. At some observing angles the images would even appear to float above the surface rather than below. Some handprint images were quite sharp, with the surface texture of the paper towel clearly visible as in Fig. 2 below.
