Illusions

Recently I came across an amazing pavement artist..Julian Beever. He can create a 3D illusion using a 2D pavement. We all have drawn perspective drawings which was held perpendicular to the line of vision...but this is drawn on a pavement, which is parallel to the normal line of vision. Here's an example.

This is only a drawing...see that people are avoiding the hole. I think these are drawn the same way post-renaissance artists drew biblical images to create a illusion of depth on the walls. Eventhough I know very little about Art in general, I know for sure that this is the one I will pay for !!

Hats off to you Julian !!
