A plurality of relatively rigid elements for arrangement into a three-dimensional (3-D) structure that represents an image; also a method for arranging a plurality of relatively rigid elements into a 3-D structure. Each element has a base-thickness and comprises a top surface, an undersurface, and a wall-surface around its perimeter. The perimeter of each of the elements yielding the image, is shaped to represent a component of the image. The elements are adapted for initial arrangement wherein a juxtaposed wall-surface of each adjacent element comprises a beveled plane. In the initial arrangement, the undersurface of two or more elements can be arranged in a pattern of the image such that beveled planes of juxtaposed wall-surfaces are frictionally-unlocked. The elements are also adapted for positioning into the 3-D structure wherein at least a portion of juxtaposed beveled planes are in releasable friction-interlock and top surfaces of elements are tiered with respect to any adjacent element(s). Images for the 3-D structures can be selected from a wide variety of recognizable images as well as abstract graphic images. Beveled planes of juxtaposed wall-surfaces matched for releasable friction-interlock can be oriented as a declining and inclining sloped pair, or vice versa.
