Fig. 1. Tensegrity structures. (A) Triple crown, a tensegrity sculpture, by the
artist Kenneth Snelson, that is composed of stainless steel bars and tension
cables. Note that this structure is composed of multiple tensegrity modules
that are interconnected by similar rules. (B) A tensegrity sphere composed of
six wood struts and 24 white elastic strings, which mimics how a cell changes
shape when it adheres to a substrate
(Ingber, 1993b). (C) The same
tensegrity configuration as in B constructed entirely from springs with
different elasticities.
