Stylized microscopic illustration of cellular structures: white folded membranes, a geometric white sphere, orange molecule, blue stalks.

Cryo-ET (tomography) slice; cristae fold into ever-smaller invaginations, each layer doubling like Cañon de Chelly strata; at the theoretical limit of resolution the cristae open into a void whose cross-section is a 120-cell (4-D polytope); the ATP synthase stalks are 10 nm tall, but their spacing follows the same 12-fold geometry as the Neolithic circle; color: ice-white membrane, cobalt motors, and the single ATP molecule caught mid-synthesis rendered as a vermilion jewel; volumetric fog added to imply the 4-D depth that the electron beam cannot reach See more
