Dampening a "Look At"

I wanted to try to make something always face the direction it’s moving in. I came up with a kind of cheesy method in which I make a second invisible object lag behind the main moving object (using a lag chop) and then setting the Look At parameter of the main object to the second object. It works, but I’d like to dampen the rotations that result from the “Look At” to make it more natural. How can I read these rotations back into a CHOP?

Thanks,
Michael

While I never figured out how to read this information from the Container, I did realize I can make the same calculation with an Object CHOP… so, I’m doing that instead.
