Relativistic Nodal Precession from frame dragging of the innermost disk regions. The hot inner flow is represented by a rotating sphere, the accretion disk is given in a color code that represents the degree of illumintation. In this case θ=60° and φ=90°. The second animation below show changes in the overall emission from the source. All details are available in Ingram et al. 2012, MNRAS, 427, 934.
