Impossible objects

Impossible objects are visual illusions or designs that cannot exist in three-dimensional space, despite appearing plausible in two dimensions. They are often created through clever perspective and geometry, tricking the viewer's perception. Classic examples include the Penrose triangle and the Penrose staircase, which seem to form a continuous loop but would require an unrealistic arrangement to exist. These objects challenge our understanding of spatial relationships and highlight the brain's role in interpreting visual information, making them intriguing subjects in art, psychology, and mathematics.
