DOM-Drag is a lightweight, easy to use, dragging API for modern DHTML browsers. I wrote it while working for Mediacode (bought by Yahoo - go team!) because everything else I could find was huge, slow, and painful to work with.
It's a little non-conventional and experimental in setup. So if you need something super robust and flexible for an professional application, DOM-Drag is probably not the right choice.
Howerver, I have used this library frequently to add simple to moderately complex effects to otherwise static HTML/CSS layouts.
