The prompt for Genuary 2024 Day 8 is Chaotic Systems, Day 22 is Point-Line-Plane and Day 24 is Undecided Geometry
The Chaotic systems can be heard through the sound design in this SonicPi Coded Composition. To reinforce the chaotic system, usage of geometric and linear algebra equations were used to control the sound.
The Point to Plane and Line to Plane equations were the linear algebra components used to create the sound. Then an assortment of those return values were then integrated in the circumference equation to bring a sense of undecided geometry.

Points to Plane

Undecided
But reminded
That the path isn’t only the plane
So, Chaotic they get
