Japanese artist Yusuke Asai uses nothing but natural pigments and water to create his intricate large-scale murals that he calls "earth painting". The materials of his works are almost always collected on-site, or site-specific, made using a variety of different textures and types of local mud, dirt and dust. Each piece begins with applying masking tape to walls, then drawing shapes of plants and animals over it to create infinitely swirling images. Asai rejects commonly used art supplies that are manufactured in favor of mud, a sediment where microscopic organisms make their home, for its special connection to nature.
