I have done several 3 dimensional wall objects.
Some are made of chipboards, formed and painted, like the three flower objects bought by The National Foundation for Art in Public Buildings.
”Flower Power” is a series of 4 pictures. They were purchased after an open competition about public art in Oslo Airport, Gardermoen. The basis for this was quadratic boxes made of peforated aluminium. These were to be placed in the floor, underneath the floor level, in the arrival halls of the airport. Glass plates are covering the boxes, fitting in with the tiles of the slated floor. The boxes are lighted by fiber optic, hidden behind their walls and shining through the holes. The boxes are grouped 4 and 4 (6 rows in all).
