Abstract: A modular element for constructing furniture or artistic sculptures comprising a flat member having three equilaterally arranged legs and three equilaterally arranged, arc-shaped sides having equal radii of curvature, each of the legs having a slot extending through its thickness and arranged equilaterally with the slots in the other legs. Groups of four elements are assembled with a center element being engaged at each of its slotted legs with a separate slotted leg of one of the other elements. In one preferred embodiment a group of twenty such elements are so assembled to form an artistic sculpture.
