Julian Beever is an English artist whose work has appeared on pavement all over the world.
He creates jaw-dropping illusions with mere chalk, and he delights us by mounting them, not on the wall of a gallery or museum, but on the crowded and cruddy streets of our cities.
His closest relation among speakers would be a street poet, storyteller, or stand up artist who could work in a park or plaza at lunch time–someone who could earn a living by astounding the casual passerby.
I urge you to visit his site.
