The works of the French-Swiss artist, Guillaume Le grau, also known as "Saype ", are huge paintings created on the grass using an airbrush. He paints his works with biodegradable paint, which he makes from water, flour, linseed oil, and natural pigments. These paintings are always on a large scale, reaching up to 1.5 acres in size, and can only be viewed from above. The artist uses a drone to monitor the progress of his work and make immediate corrections. Unfortunately, these paintings have a short lifespan, lasting only a month, as the paint used is not permanent.
