Folding polygonal toy construction element

A toy construction element in the form of a polygon comprising a substantially flat body portion having four or more edge faces of substantially equal length and top and bottom faces, each edge face having formed thereon a plurality of outwardly projecting integrally formed connectors adapted to connect with corresponding projecting connectors on an edge face of another construction element in a snap-together lateral interlock between adjacent elements while permitting hinging action between connected elements on an axis parallel to the connected edge faces,

• wherein said construction element has at least one line of reduced thickness extending across the body of the element from apices of the polygon and through the center of the body of the element to form at least one living hinge which separates the body of the element into at least two equal triangular portions joined by at least one living hinge, the three sides of each triangular portion including at least one living hinge and at least one edge face.
