Extirpation

So as of now we have:
Grass and butterflies that react to the prescence of people. They will accept 5/6 (how many position co-ords are you sending me?) people’s positions and the grass parts for them, and the butterflies scatter.
Based on the overall health, their saturation fades, and the butterflies’ population is decimated.
The tree(s) wilt and then the leaves fall off, based on the local health (which is based on how people have been behaving in the zone directly around it)

Still to do : the face leaves.
the idea where we take pictures of people as they enter and have their faces printed on certain leaves – so the difficulty lies in that the trees are prerendered for maximum visual goodness, but it means i can’t retexture them. So I have realtime cards with faces, however – how to integrate them into the prerendered trees? hmmmm
