# Genuary2025_BlackWhite

# 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

```ocaml
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
```

## Code

### LiveCodeLab

```javascript

if time % 15 > 10
	background white
	fill black
	stroke white
else if time % 15 < 5
	background black
	fill white
	stroke black
else
	background white
	fill white
	stroke black

3 times
	scale sin(wave(0.003))
	rotate 
	move 
	ball
		ball 
```

### Hydra

```javascript
s0.initScreen()

src(s0).scale(1.5).repeat(()=> time % 5 + 1, ()=> time % 5 + 2).out()
```

### SonicPi

```ruby
#using 6 circle families to make the sound as Pi=4

=begin

using the various circle related equations to make two set of Circle Families and their members to
make sound

turning pi into 4
