Motion Paralax

Motion ParalaxOur perception of space is produced, in part, by parallax, the shifting relationship of objects in space depending on our view point; even the simultaneous different viewpoints of each of our eyes give us a clue to spatial depth. Try looking out of one eye and then the other - notice how objects shift in relation to each other. Two patterns on top of each other with at least the top one semi transparent will interfere with each other. The points where the two patterns cross each other become the visually dominant pattern called a moire'. This interference pattern or moire' shifts position if the two original patterns move in relationship to each other. If the two original patterns are even slightly separated spatially, and the viewer moves the moire' also shifts because of parallax. Even each eye of the viewer also sees the interference points in different locations. Both the moire' and parallax experiences are common in everyday life. When driving under a bridge, the bridge railings often create a moving moire' pattern. The feeling that you are racing with the moon on a nighttime car ride is misinterpreting space as movement because of parallax. Bunts' work sometimes has areas of moire' patterns in it. Because of parallax, the interference effect creates the appearance of a space moving away from the picture plane, or the appearance of movement, or both depending on how the mind interprets it. Bunts wanted to make this mental interpenetration of space and movement part of his essentially flat work. An attempt to express this effect digitally is the movement in the work seen when you move your cursor over the work and the cursor changes to the icon of a figure (that is supposedly looking at the picture).
