Artists such as Abdul Latiff bin Mohidin take inspiration from the local tropical landscape as well as architectural forms specific to Southeast Asia. His famous Pago-Pago series is composed of statements inspired by the tribal arts of the Pacific islands, from the natural environment and from temples of Southeast Asia. This series exemplifies his attempts to make visible the mysterious forces and presence of nature. He makes use of the black outline as a means of creating tension as well as harmony among the diverse forms. This suggests the influence of his studies in Germany in the 1960s where he took an interest in both German Expressionism and the art of indigenous peoples that he saw at the Berlin Museum of Anthropology and Oceanic Art. At first glance, his thickly outlined forms, ample brushstrokes, jagged and round edges, textures, and patterns seem abstract. On closer examination one finds biomorphic forms such as bird and plant forms, ships and elements of temples. These motifs lose their cohesion as singular entities and blend into one another suggesting the interdependence of all forms. For instance, bird heads blend into plants, and plant forms become architectural structures.
