The 8-cell, or tesseract: eight cubic cells, Schläfli {4,3,3}. What you see is a 3D shadow of a 4D rotation — the inner cube’s scale is the W-coordinate, breathing between two projections. Pure CSS 3D. No WebGL.

The cube that contains a cube that contains a cube
Outer cell and inner cell are the same tesseract seen at two W slices. Connecting struts are the edges that run in the fourth direction. Pointer tilt yaws the shadow.

C⁴ → ℝ³ · inner scale = π_W(R_{XW}(t)) · 12 faces × 2 cells + 8 W-edges
A tesseract has 8 cells, 24 faces, 32 edges, 16 vertices. This chamber shows two cells and the W-edges between corresponding vertices. Iridescence is a pair of linear gradients, not a texture map.
