"Magnetical" Human Contour

Hi All,
I post this topic in the beginner section cause I’m actually a newbie with OF, but I have good experience with Max/jitter and QuartzComposer. I’ve already did a search for what I need but I preferred open a specific topic.

This is my idea:
a wall-projection of various very simple objects. When someone puts in front of the wall, a webcam recognizes him and his (as more detailed as possible) black shape or contour is projected on the wall. Simultaneosly, the human contour attracts the objects, moving and placing them all around the contour.

Which kind of libraries or resources do I need for my idea?

Thank you and sorry for my horrible english : )

D.

up! :smile:
