Interactive Street Trompe L'oeil

From an unknown artist we have a series of paintings that all look like they have been drawn in the same city, perhaps even on the same street. These Trompe L'oeil are quite interactive and pedestrians alike seem to enjoy taking part in some of the illusions. One more bonus image of a beautiful lady blending in with a wall using body paint.

Edit: After closer inspection, the pedestrian in some of the photos might be the artist himself...notice the small box of crayons lying next to him.
