Iridescent Soap Fractal Draining in Yekaterinburg Arcade

Honey-colored light floods the glass-roofed arcade in Yekaterinburg, illuminating a fractal pattern of soap film draining in rhythmic geometric stripes. The iridescent surface shifts from copper to soft violet as the liquid flows downward, creating thin, web-like lines that segment the colorful expanse. Polished surfaces below catch small, sharp highlights from the midsummer sky filtering through the overhead glass. The pattern expands outward in a precise, mathematical dance, with the film's thickness varying to produce bands of shimmering color. The copper-toned glow deepens the warm hues, against the cool, reflective sheen of the wet film. A final edge of the bubble catches a bright, metallic reflection against the darkening interior.
