This specimen is part of a series of three posters that show the transformations and distortions possible with the Pantograph — an instrument to duplicate drawings to an adjustable scale. This invention of Christophori Scheiner (°1573 – †1650) consists of four rods connected through four pivot points. These deformations are made by Lu Liang and Dries Wiewauters using a Pantograph constructed by the latter, out of four strips of one meter aluminium. Each rod of this Pantograph has seven possiblities. This makes for 49 possible combinations of which the center one is a proportional copy — at a scale of 200% — of the original triangle.
