We are currently reinvestigating the use of Tr(K)=constant surfaces as a possible foliation in the numerical simulation of black holes to support the gravity wave interferometers (LIGO). Preliminary indications suggest that families of such surfaces (1) avoid singularities and may avoid the need to excise the apparent horizons, (2) are asymptotically null aiding in gravity wave extraction, (3) cover the spacetime, and (4) appear to have manageable "grid stretching" properties. Numerical investigations into their utility are currently underway.
