To ease myself back in, I applied this tutorial to the firefly antennae. It uses spline IK and spring controllers to create secondary motion. This means, for example, that if I animate the head rotating, the antennae will follow naturally and flex at the beginning and end of the motion. Spring controllers have regular PositionXYZ controllers as children, so you can still use the spline IK helpers to shape the antennae.
I had no idea that the spring controller was able to take forces into account. This opens up a lot of interesting possibilities.
