The Large Tensegrity Sculpture was made from salvaged metal tubes from a discarded lawn chair. A tensegrity (short for ``tensile integrity", probably invented by Kennith Snelson) is an object made of rigid rods which do not touch, but which are held in fixed positions by flexible cables. The geometrical arrangement of the rods and cables is such that any displacement of the position of any rod would stretch some cable. The mathematics of these objects has been extensively studied by Prof. Robert Connelly (Cornell University).
