Here are preliminary concept designs for the trees and trojan virus. For reference, I looked at the trees from the game Okami. I liked the dead look of the trees in Okami. Since the trees are infected in our project, I figured a dead, sharp look was appropriate. Our user is going to be able to disinfect the trees. When they are healed, the red lights on the tree will turn green. Oscar, Rheeny, and I tested out the red to green animation on the trees.
