Frame of Reference

2006. Series of ten objects, silkscreen on acryl glass
Each 50 x 50 x 50 cm

This is a series of objects made in transparent acrylic glass, with grids printed on their surfaces. The printed pattern causes a multi-stability, perception phenomenon, it creates perceptual shifts from three to two-dimensional understanding of space.

In our perception there are three dimensions, which we ascribe to a physical space. These dimensions play a fundamental role in our comprehension of the world around us. The orthogonal grid we habitually project onto our surroundings creates our frame of reference that largely defines the ways in which we can navigate a particular ambiance. It forms the a priori background within which we perceive spaces and measure our position, motion and orientation towards them.

Frame of Reference 1- 4

Frame 1 is a cube divided by a regular orthographic grid. It is our default perceptual framework.
Frames 2-4 are distorted cubes - irregular polyhedra, designed after two-dimensional representations of the cube (Frame 1). Axonometric, isometric and perspective drawings - projections of the cube are literally translated into three-dimensional objects while all the geometric distortions are kept. The grid within the objects follows distortions. A three-dimensional objects are objects follows distortions.

Frame of Reference 5 - 7

Frame 5, 6, and 7 are transparent acryl-glass objects - cubes with different poyhedra imbedded within the cube: stellated octahedron, cuboctahedron constructed by intersecting hexagonal planes, and cube divided by intersecting diagonal planes. Base orthogonal grid printed on the cube is superimposed over diagonal trajectories of faces of polyhedra causing perceptual switching between two and three dimensions.
Objects play with the principle of perceptual ambiguities caused by contextual modulation. When our frame of reference is lost, our attention becomes multistable, it shifts in search of meaningful interpretation.

Frame 1

Frame of Reference 8 - 10

Frame 8, 9 and 10 are cubes with internal divisions that expand dimensions conceptually. Frame 8 and 9 are projections of higher dimensional polyhedra onto the cube - a hypercube and cube pyramid. Frame 10 consists only of orthogonal grid- based constellation of dots which in theory leaves to the viewer open possibility to imagine any-dimensional space
