A huge grain elevator and silo in North Dakota are the site of a massive mural by an Australian artist. Guido van Helten has been working on the project in Minot for over a year, and when it's finished, it will be visible across town. He has painted similar murals in the U.S. Midwest as well as in other countries around the world. The artist says that when he creates murals on large, old structures, “it becomes part of the landscape.” The mural will cost about $350,000 and will be covered through donations.
