Alice has Class(es)!
Objects are created from classes.
Class set of specifications that describe a particular “type” of object.
Each item found in the Gallery is a class.
Each time the class is used, it is an instance of that class.
Gallery is a collection of different object types (animals, beach, people, etc.).
Two galleries are used:
Local gallery (stored on computer)
Web gallery (maintained by creators of Alice)

These dimensions are
part of 2D objects
Depth

3D Movement
Forward is perceived as the object getting larger as it gets closer to us.
Backward is perceived as the object getting smaller as it gets farther away from us.
Motion is based on OBJECT’s perspective…our left is the Coach’s right
