and for the source: https://github.com/voloko/facebook-circles/tree/master/src/view

Not jquery, but using UKI javascript library

I would start with jQuery UI's draggable: http://jqueryui.com/demos/draggable/ Then add a little CSS / hover type stuff. Is that what you were looking for or you want something more specific?
