When you read a piece of writing, you may notice that there were decisions made that are carried through it. The longer the work, such as a novel, the more obvious those decisions generally are.
For instance, if an author wants to be able to switch between characters' thoughts and feelings, as well as their actions, they may opt to write in 3rd person universal. If they want a more intimate feeling within one character, having the reader experience only what the protagonist experiences, they may choose to write in 1st person.
What person you write in is only one choice an author makes. Pace, default tense (usually either past or present), setting - these are all decisions that are made initially and carried through the entirety of the work. (Usually. There are exceptions!)
In this system, each decision is called a Pip.
The collection of Pips, the point of view, the setting, the pace, etc, constitute a Pod.
In Pips World, you are encouraged to make these decisions for each chapter/episode.
At this point, you may be wondering if the continuity of a work will be interrupted by having different pods, a different set of pips, in each chapter. Maybe. But we think the freedom of using different pods for each of your chapters/episodes is what makes this fun.
Try it. Experiment. Have fun!
