Meissner Effect.

Indivisible (Unrealized Proposition) is a plane of superconductivity that levitates multiple participants upon pod-like speakers that orbit around one another. The project applies the Meissner effect to create vibrant colors, levitation, and sound as electricity moves from the body into the speaker then into the supercool mist below.

In the massive fog filled space the orbits of any two people are carefully controlled to the time it takes to pass someone on the street, while all pods exhibit the gravity of planets and stars in a solar system.
