A multi information display device using square cross section members side-by- side, arranged in groups of two (single row display, double side viewing), or four (two rows display), or six (three rows display), providing correspondingly four or eight or twelve different display surfaces. Each said group is attached at top and bottom to mechanisms, driving said members in an oblong close loop motion, perpendicular to display surface, thus increasing the distance between members in curved portion so that pins and guides cause turning with 90dgr about their longitudinal axis for the next display surface, and the two or four or- six members of said group are circularly changing position, and moving through 1/2, 1/4, 1/6 of the oblong close loop length so that each face is cyclically brought into display surface position All said mechanisms are mounted to display device frame, and driven by a single motor.
