Julian Beever is an English artist who has been creating 3D chalk drawings on pavements since the mid-1990s. He makes his art using a projection technique called anamorphosis. When viewed from a particular angle, this technique creates the illusion of 3D.
Beever’s “trompe l’oeil” (”trick of the eye”) chalk art is so convincing that people try to avoid potholes he has drawn in the pavement.
According to the author, the “secret is to set up a camera on a tripod and keep it in one spot and check every mark you make. It’s really just playing with perspective to make it appear different to what it really is.
