Years with an HN recommendation, 2007–2026

Cited as the go-to example of hyperbolic geometry made intuitive through VR.

Henry Segerman and collaborators demonstrate virtual reality experiences in non-Euclidean spaces, including hyperbolic and mixed hyperbolic-Euclidean geometry. The browser-based demos let viewers move through these spaces and show how strange the geometry feels from inside.

I'm cautiously optimistic about VR as a tool for teaching and understanding math up to three dimensions. You may have seen the "Non-euclidian virtual reality" video floating around YouTube ( [this video] ).

reminds me of the demonstration of hyperbolic geometry in VR by Henry Segerman ( [this video] ). there is a browser demo too where you can 'fly' through the small world ( [link] )
