Hey it’s Sara today,
I always was inspired by these 3d artists who would paint/draw on sidewalks to make it so realistic. It’s so 3d that it looks as if the people in the picture are a part of the art. The art is called anamorphosis where the artist creates the illusion of three dimensions when viewed from a different angle. It displays the artwork of Edgar Mueller, Julian Beever, Kurt Wenner, Manfred Stader, and Eduardo Rolero. It takes a lot of talent to be able to make something seem as if it’s popping off the street/paper.
