BEGIN_DESC
Two connected delta gliders demonstrate the effect of gravitational field
gradients on distributed vessel masses. The system swings around its tidally
locked equilibrium state. The camera is pointing towards the centre of the Earth
to demonstrate the effect more clearly.

Make sure that "gravity-gradient torque" is enabled in the Launchpad dialog.
Speed up the simulation to 100x.
