KAngaroo Physics component

I just watched an old tutorial on a Kangaroo caternary curve.

I can't find the component (Kangaroo Physics Engine?) that makes it all happen in my more recent GH version 0.9.0075.  Not sure what version the video was done with but it was at least two years old. I found the caternary component in GH but want to use the force finding time feature that the Kangaroo shows. Any suggestions to what that old Kangaroo component has evolved into now?
