In modern times, the term became more well-known with the Mexican muralism art movement (Diego Rivera, David Siqueiros and José Orozco). There are many different styles and techniques. The best-known is probably fresco, which uses water-soluble paints with a damp lime wash, a rapid use of the resulting mixture over a large surface, and often in parts (but with a sense of the whole). The colors lighten as they dry. The marouflage method has also been used for millennia.
Among minor artists who have made Berck a subject in their work are Paul Laugée (1853–1937); Eugene Chigot (1860–1923), who had a studio there in 1893; and Georges Maroniez, a judge who painted and photographed in the area during holidays. Two others stayed in the town because of its medical facilities. Albert Besnard was there in 1895 on account of his tubercular son. As a thanks offering for his cure, Besnard and his wife Charlotte decorated the walls of the chapel in the Cazin-Perrochaud Institute between the years 1898-1901. While he was there, he also executed oil paintings and etchings. Jean Laronze (see above) was also there in 1904 for the same reason and painted several canvases during his stay.
Banksy has published a "manifesto" on his website. The text of the manifesto is credited as the diary entry of British Lieutenant Colonel Mervin Willett Gonin, DSO, which is exhibited in the Imperial War Museum. It describes how a shipment of lipstick to the Bergen-Belsen concentration camp immediately after its liberation at the end of World War II helped the internees regain their humanity. However, as of 18 January 2008, Banksy's Manifesto has been replaced with Graffiti Heroes No. 03, which describes Peter Chappell's graffiti quest of the 1970s that worked to free George Davis from imprisonment. By 12 August 2009 he was relying on Emo Philips' "When I was a kid I used to pray every night for a new bicycle. Then I realised God doesn't work that way, so I stole one and prayed for forgiveness." A small number of Banksy's works can be seen in the movie Children of Men, including a stenciled image of two policemen kissing and another stencil of a child looking down a shop.
Many home owners choose to display the traditional art and culture of their society or events from their history in their homes. Ethnic murals have become an important form of interior decoration. Warli painting murals are becoming a preferred mode of wall decor in India. Warli painting is an ancient Indian art form in which the tribal people used to depict different phases of their life on the walls of their mud houses.
