Three interwoven hollow loops approximate the familiar folded, multi-lobed visual language of a projected Calabi–Yau section. They distribute air; they are not claimed to be a literal six-dimensional manifold.

Calabi–Yau Vane
A hollow-tube, Calabi–Yau-inspired cage floats inside a spherical air bearing, itself enveloped by geomagnetically responsive steel balls. The upper arrow follows wind; the lower magnetized needle follows magnetic north. It looks perpetually lively because its environment is not still.

The explicit rules preserve energy, scale compatibility, and smooth voice-leading. A small online learner adapts pitch-class preferences to configurations actually visited. Relaxation lets those two forms of intelligence negotiate each note.

Steel spheres form a flux-sensitive envelope. The inner body is supported by externally supplied air. Geomagnetism supplies compass torque, not lift.
An Earth-field-only ferromagnetic suspension is the intentionally impossible version: ordinary static magnetic arrangements cannot provide stable free-space levitation, and Earth’s field is only about 25–65 µT. The manufacturable concept adds an air bearing; wind and supplied pressure are energy inputs, while drag and leakage are losses. Output never exceeds input.

Sixteen paired air microchannels alternately draw inward and drain outward as pressure, wind, temperature, and humidity change. Sensors and passive valves would measure this weather-driven motion. It is deliberately separate from the dark-matter model.
The faint streams visualize dark-matter phase-space trajectories through local gravitational potentials. Gravity has no known distance cutoff, so the apparatus and dark matter interact gravitationally; predicted tabletop coupling is nevertheless exceptionally small. The drawing does not claim capture or propulsion.
detected: a controlled residual clears the declared threshold. bounded: none does, so report an upper limit. ish: sensitivity or assumptions cannot yet distinguish the hypotheses. Smallness is modeled; instrument limits are never recast as physical absence.
H₀: measurements match the local-halo, gravitational-background, weather, vibration, thermal, magnetic, and airflow model; no device-correlated residual remains. Two-sided H₁: a nonzero residual of either sign tracks orientation or state after controls. A t-test is used only for suitable independent residuals; otherwise the analysis must use the error model the data actually support. Jupiter-scale gravitational capture and scattering motivate the model—not an assumption that a tabletop mass produces a detectable signal.
“Calabi–Yau” here describes visual inspiration from a 3D projection/section. In superstring compactification, the internal space has six real dimensions; this CAD object is an ordinary three-dimensional educational instrument.
