  The presence of magnetic monopole like excitations of nonabelian varieties is
one of the subtlest consequences of spontaneously broken gauge symmetries.
Important hints about their quantum mechanical properties, which remained long
mysterious, are coming from a detailed knowledge of the dynamics of
supersymmetric gauge theories which has become available recently. These
developments might shed light on the problem of confinement and dynamical
symmetry breaking in QCD. We discuss here some beautiful features of
vortex-monopole systems, in which dual nonabelian transformations among
monopoles are generated by the nonabelian vortex moduli.
