Glass Sphere Light Refraction Fluorescent Lobby Midnight

A clear glass sphere rests on coarse sand spread across the polished concrete floor of a ribbed industrial lobby. Stark fluorescent tubes overhead cast harsh, linear shadows that slice through the dark room. The sphere catches the overhead light, fracturing it into a spectrum of muted reflections that ripple across the floor. These geometric patterns stretch outward, mirroring the ribbed texture of the concrete walls above. The scene remains cool and precise, with the sand grains visible between the glowing arcs of refracted color. The light shifts from bright white at the sphere's center to soft blues and grays at the edges, ending in a sharp, fractured highlight on the concrete surface.
