Continuing my series exploring pieces of my poi math paper step-by-step. I've previously gone over the basics of the math and how to use it to model simple flowers and third order motions.

Four months ago, Jon Alvarez asked a seemingly innocuous question on the Poi Chat forum on Facebook that led me to one of the most mammoth undertakings of my adult life: has anybody set down definitions of all the poi moves in one place? The answer is sadly no, but it got me thinking about why that answer was no...beyond whether someone had set up a dictionary or encyclopedia, to the very heart of how we define poi tricks and discuss them online.

People frequently reference the math behind poi on many forums and groups, but it can seem a little daunting to folks that don't have that kind of background. Here's an attempt to level the playing field. A lot of this will be review for the more mathematically inclined folks out there, but for those who aren't, hopefully this will give you the Cliff's Notes as to some of the math we use to describe flowers and the like and make it a little bit more digestible. If you like this, please leave me feedback as I've got plans in my mind to do a whole series of these kinds of videos :)
