Night time
The models are the same for day and night. The sun will be off at night and the moon will be activated. The moon has less intensity and a blue-ish light color, but to be honest it does not make much of a difference. The grove will be illuminated by street lamps and the lights from some of the rides. Here's some screen shots from the night view.
Sounds
There are three kinds of sounds in this environment. First is the ambient 2D sounds which can be heard equally from any location. Second are the 3D sounds which have a source and get louder as you get closer to their source. The last kind is the sound of talking, which can be heard if you get close enough to some of the people. Here is a list of sounds for each kind.
Ambient:
Sound of the street (cars, wind, ...)
Sound of birds
Sound of crowd
3D Sounds:
Sound of the Carnaval (Which is attached to the swing set)
Sound of a conversation between two people
Sound of water from the fountain
Sound of dog barking in the dog park
Sound of a dog yipping in the dog park
Car horn which is played only when you click on it
Talking:
The woman at the table asking is you want to buy tickets
The woman on the bench laughing (the animation is not playing yet) asking if you want to hear a joke.
The man (who is supposed to be your friend) asking how you are doing.
