Fruut are a class of transformers sourced from EGP, and translated into the main geometrical primitives: rectangle, circle, and triangle. For identification purposes, we like to say that each shape corresponds to a 'fruit'; respectively: blueberry (alpha helix), banana🍌 (beta sheet), and lime🍋 (gamma valley). The fruut are part of the Stewdio's kit (complementing the flageolet) for transcoding (the parameters of) twistor fields so as to establish both intonation+melody/groove of The Origamic Symphony.
In time signatorial mode, fruut are the tools used for folding stews to derive (arrive at) a fibor.

It is assumed that the shapes are true (ie. two-dimensional) by default, and can occupy higher dimensions of uuater (world volume).

Notes (+): +It is prerequisite that mathematics begin with primitive notions. Hence, when postulating, we start at some angle and navigate from there.

+Geometric primitives are called such because they are the building blocks for other forms and shapes.

+The melody is a secondary actor in stew choreography (ie. essential for closing an l-string generated from its walk).

+Rule of thumb: fruut is for folding, and the flageolet is for arrangement.
