VIDEO

(background music: Fully Alive by Flyleaf)

This video shows the movements of the elevators and bridges that emphasise the action and interaction with the environment.
There is a rotating sphere shape above the meeting place and will move down when meeting is occurred to provide light. It also cast interesting shadows to environment. I use the area trigger for the moving shells outside Helen's office and the chairs and moving sphere over the meeting place. The entities will only move when people walk throught the area.
The texture applied on the entities help show the moving direction.
