Overview

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.

none-2D surface things: * 1D: MIDI (music) * 3D: CNC mill/ 3D Printer * 4D: VR (animated) * outright Non-Euclidian: [VIDEO]

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

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 ( [VIDEO] ).
