Overview: The start state is on the left initially. Moving gears represent active states and transitions represent smaller gears placed between the moving "state" gears.
Model Templates: FSM= Finite State Machine.
Metaphors: Large gears as states. Smaller gears as transitions. Current state is a moving gear with a bubble rising into it.
Simulation: Viewpoints: Initial, By-State-S1, By-State-S2, 4 other interesting viewpoints. Execution: press white block on left and then transitions to cause the machine to move from an active state to a target state. S3 and S4 are "final states" from which there are no transitions. Animation: gears move to indicate a state transition. There is a blue bubble that deflates in the source state and inflates in the target state. Audio: mechanical sound during state transitions.
Modeling PROTOs constructed: StateExtender, StateBottom, StateTransition, SpinningGear, GearBase, GearTransition
Modeling PROTOs used for this world: StateTransition (a State in the world), GearTransition (a Transition in the world)
