Rotated Surfaces

  • Jürgen Weber


There is a third way of distorting the screen, which leads to other conclusions. If we consider flat, screen-like, identical cubes, set next to each other, as in a brick wall, for instance, we then have a unit of the lowest degree. The cubes are all interchangeable; it makes no difference to the appearance. Looked at from the front, it does not seem at all spatial. There is no perceptual information about the material make-up of the screen. If we now rotate these cubes on their vertical or horizontal axes (258–260) we see a dramatically spiralling process, demonstrating a spatial movement of rotating cubes or surfaces. It instantly becomes a unit of a higher degree. None of these gradually rotated cubes could be interchanged without confusing the picture. Although neither density nor size has been altered in these screens, we comprehend the rotation of the cubes on their vertical or horizontal axis as the result of a process which considerably increases the impression of spatiality and, in addition, provides a key to our perceptual judgement of nature.
