Shape 2, an Architectural Phenomenon, Mark Lewis 1975-76
Utilising the basic shapes of two triangular prisms adjoining one to the other, having first perverted each by forming convex and concave faces, a unique shape was born. It was made using the principles of three dimensional card shape making. Each shape was drafted as a geometric pattern on to card with ruler and compass anticipating that the card would be folded and adjoined by way of gluing tabs. These would allow for the folding along scored lines in the card to form each shape. They were made as if a cardboard pyramid in the geometry class at school. The geometric card shapes were made separately as a hollow card models each opposite to the other. One was then affixed to the other to form the whole shape. It having equal and opposite concave and convex faces, top, sides and bottom. This formed the pattern to make the mold to cast the shape. The block now a solid is able to be laid adjacent to its self and form an extended and larger shape to be made as a collective in various formats. A rather complicated building block or brick in its appearance the repeat modal collectively arraigned becomes the model of a building made of a repeated geometric solid for example the Sydney opera house.
