We'll discuss representations of punctured sphere groups into SU(2) with restrictions on the holonomy of the punctures. Following Fintushel-Stern and others, these may be described by polygonal linkages. We'll then discuss some aspects of the topology of the representation varieties of these groups, including results from the thesis of Ethan Street.
