flowers growing out of shadow/shilloutte

    May 31 2006 | 10:44 pm
    following concept:
    a user is crossing the lightbeam of a videoprojector and his/her shadow is appearing on the wall as a black shilloutte.
    -> now i want to have a projection of some abstract black flowers growing around and out of the shilloute/shadow on the wall.
    - how did i get the essential information of the shadow contour. what's a good angle and position of the camera and projector for doing this?
    - how did i animate and programm the growing plants?
    thanx for hints, tipps and links
