Anderson has been at the forefront of research on surface perception for decades now. He's shown over and over how subtle manipulations to images can transform our percepts in dramatic ways.
The figure here shows how the covariation of shading with object boundary conditions triggers either a perception of a 3-D corrugated surface of uniform albedo with variable illumination (left) or a 2-D surface with variable albedo and uniform illumination.
