At this point, one either sees random shapes in white (clouds? dancing person?) against a dark background or dark trunks /branches against a white background, which I believe is the intended effect. Maybe the latter will become more obvious when the balconies are fully glazed. Someone told me once that Africans regard zebras as a black animal with white stripes, while non-Africans see them as a white animal with black stripes. Perhaps a sociologist can conduct a similar survey with these towers when they're done?
