Brass Pendulum Over Sand Tray Desk

Dim blue twilight falls through a window, casting a cool hue across a wooden writing desk in Ouagadougou. A polished brass pendulum hangs suspended, its metallic surface catching the warm glow of an interior lamp. Below it, a shallow tray filled with fine sand awaits movement. The rainy season outside suggests a humid stillness, visible only in the soft, diffuse reflections on the desk's polished edges. Negative space frames the apparatus, isolating the brass against the darkening room. A faint shadow of the pendulum rod stretches across the sand, marking the precise moment before motion begins.
