These swingers approaches a target value, kinda like the Zip or the Slide, but has a few parameters that enable it to approach the target in a non-linear manner as opposed to the aforementioned modules.

Other possibilities for similar effects would be bounce, slow-to-fast, delay or a wait-for-target-to-stop-changing.
Another neat possibilitie would be a module that doesn't stop when reaching a target, but calculates interia while the target is changing and slows it down based on inertia after dragging is stopped; allows you to drag&throw instead of drag&drop
Note that if you want to use this to drag stuff around (i.e. windows, controls), you'll need to make the drag area itself invisible and non-swinging.
