Inspiral of Equal-Mass Black Holes with Spin Anti-Aligned to the Orbital Angular Momentum and of Magnitude 0.95
The spins have magnitude 0.95, are parallel to each other, but are anti-aligned with the orbital angular momentum. This simulation is described in a publication in Phys. Rev. D., in press. The paper can also be accesed at arXiv:1010.2777.
Movie displaying the evolution of the spin function (imaginary part, χ, of the Penrose-Rindler complex curvature, κ) on the apparent horizons
Movie displaying the evolution of the scalar curvature, R, on the apparent horizons
Note that aside from corrections that become important only near the time of merger, the spin function χ and scalar curvature R should agree well with -2Bnn and -2Enn, respectively, where Bnn and Enn are the horizon vorticity and tendicity, respectively.

Now, here, you see, it takes all the running you can do, to keep in the same place. If you want to get somewhere else, you must run twice as fast as that.
