Field notes

The app presents 4D objects as 3D cross-sections that can be shifted along the fourth axis, w. Its eight named scenes include a physics sandbox, regular 4-polytopes, knot manipulation, the Hopf fibration, hyperbolic and spherical spaces, a mirrored Klein-bottle room, and slices of 5D/6D quasicrystals. The page offers desktop mode and says Meta Quest hand tracking is supported.
