Signal Flow Assignment
- A process you are interested in
- Inputs?
- Outputs?
- Switches, junctions, choices?
- Different outcomes? Consequences of Decisions?
- How are things related?
- Flow chart, system, map or circuit?
- At least 10 elements / components

PRACTICAL SYSTEMS
- Railways / train stations
- Freeways, city streets
- Computer networks
- Chemical reactions
- Electric circuits
- Decorations
NETWORK MAPPING
- Start with a Wikipedia or other article on a subject
- Note what it is connected to
- Continue noting connected articles until...
Fictional ideas
- Unicorn migration patterns
- Colonize the solar system
- Haunted House plan
- Infernal machines
- etc...
Feedback Loop
A system where the output loops back on itself and feeds into the input. This often creates a runaway effect. Loops that get bigger and bigger are called positive feedback loops. Loops that get smaller and smaller are called negative feedback loops.
Feedback loops examples
positive feedback loop
Feedback loops examples
positive feedback loop (from a zombie perspective)
Zombie outbreak
Zombies infect humans
Human population drops
Infected humans infect
more humans

Equilibrium...
The populations keep each other in balance, population growth loops are kept under control.
Stampede!
Positive feedback loop
Feedback loops in audio and video
The amplified audio goes back into the mic and gets amplified again, into infinity, which sounds like this.
The video monitor is being filmed, so a monitor with an infinite number of monitors inside of it appears, which looks like this.
How to avoid A/V feedback loops?
Keep the input away from / not pointed at the output!
