CAPTION to the sequence of Figs. 25 thru 31: A Progression in Tensegrity structures from simple to highly complex is seen on these two pages, culminating in the sphere (Fig. 31), model for a forty-foot, 270-strut sphere which was built at the University of Minnesota in 1953-54. Note that compression members do not touch (they are not continuous), but the only continuous, cohering force is tension.
