Ha! the title of that video "Spherical Geometry Is Stranger Than Hyperbolic" is very insightful. Due to the convergence of the light rays on positive curvature, objects appear larger the further they are! Hyperbolic geometry is like euclidean with a spacious horizon. But spherical geometry is a wickedly different thing. All your "sky" is covered by the single point at your antipodes (when it's not occluded by a tiny object very far away from you).
