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 &amp;quot;sky&amp;quot; is covered by the single point at your antipodes (when it&amp;#x27;s not occluded by a tiny object very far away from you).</text></comment>

I got disorientated and nauseous just watching that. I can&amp;#x27;t even imagine spherical geometry with VR.</text></comment>
