"A good 3D sidewalk mural is an amazing sight to see. The first time someone sees one of these works of art they are usually surprised at how the mural looks when not look at it from the point it was designed to be viewed from. These murals are much larger than they appear from the viewing point and the images are stretched out. This is because they the drawing has to be skewed order to maintains the correct proportions. So the points far away from the viewing point will be much larger than the areas closer. Unlike wall art where you are looking straight on, with sidewalk art you are looking down at an angle, which is why a sidewalk artist much correct the perspective." -Julian Beever, 3D Chalk Artist
