Abstract: Spacetime discretized in simplexes, as proposed in the pioneer work of Regge, is described in terms of self-dual variables. In particular, we elucidate the `kinematic' structure of the initial value problem, in which 3-space is divided into flat tetrahedra, paying particular attention to the role played by the reality condition for the Ashtekar variables. An attempt is made to write down the vector and scalar constraints of the theory in a simple and potentially useful way.
