The device is in the form of a stand which can be rotated around a vertical central axis. It has a horizontal section in the form of an equilateral polygon. At least some of the display surfaces (60,60') are surfaces of two-dimensional wall elements, which can alternate between two display positions. The alternating wall elements are wide enough that one vertical side edge depending on the display position, is connected with a side edge of one of the other two adjacent wall elements. Thus, in horizontal section, the stand has the same geometric form and consists of an equilateral polygon. |
