The video explores the concept of multi-stable perception, particularly in the context of relief maps and illusions like the rabbit-duck illusion. It delves into how light and shadow influence our perception of convex and concave shapes, emphasizing the role of the sun's position. The video also discusses the symmetry in nature and how it affects our perception of terrain. Finally, it highlights the importance of cartography in accurately representing landforms, even if it means placing the sun in an impossible position to ensure clarity.
