Munan Øvrelid shows three installations in Tegnerforbundet , which is all about sensing through recording, in a range of techniques from math to drawing, photography, sound and print. The works range from graphs and calculations to images beyond human control and perspective, from objective mathematics to unique relationships. Abstractions make complex contexts visible and thus new understandings possible, but there is always something that escapes in the distance between mathematics and the object, the subject and the mathematics, the subject and the object and the object and the object. In the work "Waterfall, mountains, rock, sea, wind, Seydisfjordur, May-July 2014", Munan has let the forces of nature create sound and images through three copper plates, one lowered down a cliff in wind, one in a waterfall and the third in the sea. The vibrations in the discs are recorded with contact microphones. The movements and encounters between the sensitive metal and water, wind, rock and rock have shaped compositions which are then printed into graphic images. In another work, figures on flower growth, from seeds to wilted bouquet, are the starting point for expressive but systematic ink strokes carved into a wooden plate. Coincidentally, a pair of birds also came and built nests and got eggs and chicks in the bed. In the installation "Birds, father and mathematics, Balbakken October 2012 - April 2013", birds and weather are registered over a winter by the artist's father. He is a retired mathematician who has moved to the cabin and started bird watching and counting, in addition to his complex variables. Activities and life around a tree through seven months form such a basis for a steel graph, a series of lively ink drawings, a photograph and graphic prints from plates from the ground under the tree. A sound work, where the number of birds and bird sounds is used as a starting point for compositions, is produced in teams with Marcellvs L.
