+The **pseudosphere** is a captivating surface of constant negative Gaussian curvature, often visualized as an infinite horn. It emerges from rotating a [tractrix](/wiki/Tractrix) and serves as a fundamental model for [Hyperbolic Geometry](/wiki/Hyperbolic_Geometry), where the familiar rules of flat space elegantly diverge.
