Five circles. Five illusions. Five ways the mind constructs what isn't there. Each form holds a different optical paradox - Mach bands carve depth from flatness, simultaneous contrast rewrites identical tones, Kanizsa conjures edges from absence, Hermann grid plants ghosts at intersections, Orbison bends the perfect into the impossible. Touch them. They respond. They breathe. They know you're watching. What you see is never what exists. What exists is never what you see.
