Do you know Augustine Kofie? He is an US-American urban artist, who usually paints walls and creates mural artworks.
I recently found a nice time lapse video of the making of one of his murals and thought, that you maybe are interested in taking a look at it. In this video, he paints a wall at an old church:
“This former church has hosted many a late night event as well as a number of commercials and reality TV shows. The retaining wall is actually the buildings side stairs as well as a handicap ramp, so the shape wasn’t exactly square as most walls I paint are. I worked the shape of the wall into the left side of the mural.
5 cans of spray paint, 1/4 gallon of black house paint, some white acrylic and all of my recycled grey water helped make this piece what it is.”
