One machine, two substances. Left: a 3D wind tunnel — volumetric airflow over a wireframe wing lineage that upgrades across eras, from a WWII section to a modern delta fighter, the way the airfoil was searched in the real tunnel. Right: the same loop for robots — grayscale data clips blow onto the policy's capability manifold; each strike dents the surface and blooms a glow that spreads outward, turning it from gray to success-green, with the lit tile playing that success trajectory. Air ↔ data, wing ↔ policy, lift ↔ how well it works.
