examples

the Necker cube

Rechts oben / links unten
on the top right/on the left of down

the design represents apparently the lattice model of a cube. The two large, overlapping squares can be thereby both front and back in each case. Thus one recognizes one depending upon focusing on the left of cube down beginning, on which one draufsieht from on the top right, or a cube on the top right present, which one regards from left down.

The name goes back on that Swiss geologist Luis Albert Necker, who described the effect of the bistabile perception 1832 first at crystal designs.

Both persons run over the Schröder - stairs

the Schröder stairs

the Schröder stairs show likewise two perspective orientations. In the left field the girl the stairs runs down, the ball afterwards. The man seems to float in the area. A turn of the picture around 180°, right field, inverts the stair perspective and lets it now the stairs climb.

Krater/hills

Hügel oder Krater?
hill or Krater?

Many viewers recognize a hill in the left field, on the right of a Krater. It concerns the same picture nevertheless, only around 180° turned. The interpretation is based on the experience that objects are often lit up from above. A bright edge above suggests a hill, a dunker edge down a shade, caused by a sloping hill. In the second field it turned around exactly.

Graphic user surfaces use this effect during the screen representation of switching surfaces. A bright upper and dark lower border line lets a out-standing button assume, reverse brightness conditions a imprinted.

application in the literature

Robert Gernhardt published 1986 telling volume with the title tilting figure, with which the envelope illustration offers a double ambiguity: Before the background of a cube landscape (=perspektivische tilting figures) a figure, the “one sits tilts” (drinks).
After the analysis by Shlomith Rimmon can be regarded some narrations of Henry James as literary tilting figures, since they exhibit verbal and narrative Ambiguität.
