A tesseract rotating through four-dimensional space, projected to 2D
A tesseract (4D hypercube) has 16 vertices, 32 edges, and 24 square faces. Rotation in 4D involves six independent planes (XY, XZ, XW, YZ, YW, ZW). The outer and inner cubes you see are actually equal-sized cubes — perspective distortion creates the illusion of nesting.
