 Phantograms are related to anamorphic trompe-l'œil paintings that first appeared during the Renaissance, a famous example of which is Andrea Pozzo's fresco in Sant'Ignazio, featuring a flat area that appears to be a domed ceiling when viewed from the correct vantage point.Contemporary artists such as Kurt Wenner and Julian Beever use similar techniques to create chalk pavement art that appears to be three-dimensional.Similar effects are often seen on televised sporting events, where sponsor logos are painted onto the playing field or track, distorted so as to appear "upright" from the viewpoint of a particular TV camera.
