🧊 Higher-Dimensional Shadows: 2D Projection of a 4D Object

Interactive 2D model of how a four-dimensional polytope appears to lower-dimensional observers: a rotating tesseract, 16-cell, 5-cell or 24-cell projected first into a 3D shadow and then onto a flat wall, with 4D rotations you can drag, live edge-distortion graph and per-vertex 4D coordinates.
