We give a simple generating set for the following three closely related groups: the hypereliptic Torelli group, the kernel of the integral Burau representation, and the fundamental group of the branch locus of the period mapping.  Our theorem confirms a conjecture of Hain.  This is joint work with Tara Brendle and Andy Putman.
