This is an authored visual development, not a calculated physical outcome or a measured galaxy catalogue. A fixed, seeded network of continuous, gently curved filaments supplies a coherent final geometry. An initial diffuse population fills the same fixed volume; later strands gather from broader neighbourhoods. Regional timing differences, gradual appearance and smooth paths reconstruct matter gathering around increasingly apparent voids. Rewinding visits exactly the same history.

Geometry is illustrative, inspired by interconnected irregular voids in Cosmicflows maps. No catalogue or third-party mesh has been imported. Softly blended light populations with irregular transverse spread form the filaments; no connecting lines are drawn. Lights are sampled galaxy and stellar-system populations; their size on screen is not their physical diameter. The pressure colours illustrate the FAiM interpretation and are not a pressure solution. The 3D/4D/3D overlay retains 15-million-light-year connections; these can be smaller than a pixel in the wide view.

Reference volume remains fixed at 7.415 billion light-years per side. Development progress does not imply a calibrated cosmic age. Speed changes playback only.
