Abstract: A set of three-dimensional construction elements which removably adhere to one another for use as a construction toy or as a decorative display structure. Surfaces of the elements are substantially covered with hook-and-loop fastener material in accordance with "surfacing patterns" which maximize inter-connection flexibility. The "3-point" surfacing pattern for rectangular prisms, and derivatives of the 3-point pattern for other shapes, provide a unified surfacing system which promotes ease of use. Derivative 3-point patterns may be determined by morphological transformations of a rectangular prism with a 3-point surfacing pattern. The 3-point pattern and its derivatives obey a set of surfacing guidelines which maximizes the number of ways of forming face-to-face, edge-to-face, and point-to-face connections.
