More representation of the fusion of science and art through Andrea Attili's Persistence in Kerr Metrics [2007].
Kerr metric:
In general relativity, the Kerr metric (or Kerr vacuum) describes the geometry of spacetime around a rotating massive body. According to this metric, such rotating bodies should exhibit frame dragging, an unusual prediction of general relativity; measurement of this frame dragging effect is a major goal of the Gravity Probe B experiment. Roughly speaking, this effect predicts that objects coming close to a rotating mass will be entrained to participate in its rotation, not because of any applied force or torque that can be felt, but rather because the curvature of spacetime associated with rotating bodies. At close enough distances, all objects — even light itself — must rotate with the body; the region where this holds is called the ergosphere.--Wikipedia.

- Earth Rotating Time Lapse
Apropos of Foucault's pendulum and the illusion it produces (namely, that it's the pendulum that rotates, when in fact it's the Earth rotating below it), I came across a video that has just emerged on the interwebs, and which helps with this...
- Foucault's Pendulum
A couple of weeks ago we saw an awesome optical illusion created by a series of pendulums of gradually increasing length. Today we focus on a single pendulum, Foucault's pendulum, and the incredible insights (scientific and philosophical) that it...
