Following menu?

hi there,
I´m seraching for a good tutorial how to build a following menu?

So there`s a small button “menu” wich follows your mouse smothly. and when you click on it the menu itmes flows aout of it and position randomly arround it. the “menu” button stops to follow and becomes a “x” for example. when you click on the “x” the menu closes and starts to follo the mouse again. also the ability to drag the opended menu on the stage should be applied. have anyone ever seen a menu like this and any idea how to realize? that would be great!

thanks in advance.
