Rigging a Sign Hanging by Two Ropes

I realize this is likely a very, very simple rigging setup, but I’m just now getting into rigging.

I have a sign, hanging by two ropes. I want to lower the sign unevenly (the ropes vary their speed). The sign then suddenly drops at one point, but is caught and then pulled back up until it’s hanging properly.

I can’t seem to wrap my head around what needs to be done. The ropes themselves are always perfectly vertical, but the sign needs to be able to pivot from either rope connecting points.

I appreciate the help.

I think you might want to check out rigid body physics instead of rigging.

Well, I don’t really need the rigid body physics and I wanted to have full control over it. That may be something I try. It may work for now.
