The pix in the paper show the frame-dragging quite clearly, both when the axis is pointing at the observer, and when the axis is perpendicular to the observer. Also, the fractal effects are quite striking. Now that astronomers know what to look for, it shouldn't be long before they find similar configurations "in the wild".
