Abstract Standing Wave Pattern in Water Tank

Pale light floods the restored train terminal, bouncing off high walls to illuminate a glass tank holding vibrating water. A rigid standing wave pattern rises from the liquid surface, creating a series of uniform, frozen crests and deep troughs. The water shifts from translucent blue to white foam at the peaks, while the troughs remain dark and glassy. Quiet shadows stretch along the base of the terminal walls, marking the late morning sun. The tank rests on a simple metal stand, its edges sharp against the industrial floor. The water's surface tension holds the geometric ripples in perfect, unblinking symmetry, ending in a sharp line where the liquid meets the glass wall.
