SpheresInBW

The prompt for Genuary2025 Day 14 is “BlackWhite” , Day 12 is “Subdivision” and Day 17 is “Pi=4”

SpheresInBW uses Hydra for subdividing the sketch, LiveCodeLab for the Black&White component while the coded SonicPi composition uses pi=4 to arrange the sounds.

Poem

The motions repeat
As the Grid is seen
In black and white
With the background Scenes
Between day and night
As the motions sweep
As the pixels are seen
