Flowers moving


i’m trying to make my first flash website, but i’m quite new to actionscript…
i found this website and was thinking of putting those flowers onto mine aswell: click on “contact”

but i can’t figure out what the actionscript should look like.
i’ve already searched for some actionscripts and found objects/movieclips that follow my mouse movement, but they never stick to the floor and when they change the direction the circle scales wrong…

is there anyone out there who could help me with this, please?
thank you very much.
