A sign structure having a display, movable member and computer means creates a unique vehicle for displaying content. In one version, the movable member is adjacent to the display and substantially shields a portion of the display as it traverses thereover. Coordinated content transmitted to the display gives the appearance that the movable member is influencing the displayed content. For example, as the member moves upward an image below the member stretches in size while an image above the member compresses in size until the upper image disappears and the lower image occupies the entire visible portion of the display. This continues as the member traverses up and down over the display. The member may appear to manipulate the images by stretching, compressing, pushing, pulling and/or erasing them.
