These systems display a rich classical nonlinear dynamics and can be used for sensitive detection. Once they are successfully cooled into the quantum ground state, they promise fundamental tests of quantum mechanics in a new regime.6 pages, 3 figures, review, to appear in APS PhysicsMesoscale and Nanoscale Physicstext
