Yusuke Asai, a Japanese artist who paints with basically anything he can get his hands on (tape, pens, leaves, dust and mud…), was asked to travel to the Niranjana School in Bihar (east India) to create a mural on the walls of a classroom. Asai unveiled a sprawling, immersive mural titled “Earth Painting; The Forest of Vows.” To create the piece, Asai sourced only locally available materials which included 7 different types of soil, cow dung, water and straw (source).
