[ODE] attraction forces?

[david@csworkbench.com]

Sure, just set world gravity to 0 at the start, then each timestep call
dBodyAddForce on each body, with the amount of force you want to add
(probably inversely proportional to the square of the distance to the
object), in the direction of the vector from the body to the object.
