  The fact that neutrinos have mass allows them to possess many other
properties, like a magnetic dipole moment and a finite decay width. Theoretical
expectations for these are, however, well beyond current experimental bounds,
and the discovery of new exotic neutrino properties would indicate the presence
of (more) new physics. Here, I review some of the current bounds on exotic
neutrino properties. Neutrino experiments are unique probes of several
fundamental space-time symmetries, including invariance under CP and Lorentz
transformations. I discuss how precision neutrino experiments are used to test
some of the most fundamental principles of physics at unprecedented levels.
