Abstract.

The moduli space of cubic threefolds is the arithmetic quotient of the complementary of a hyperplane arrangement in the 10-dimensional complex ball. This coincides with the period domain of a family of hyper-Kähler manifolds with an order three automorphism. I will explain what happens to the automorphism when the cubic threefold degenerates.
