# FlowInGlow

For my fourth sketch of Mathober that is coded in **Hydra & SonicPi , FlowinGlow** will be using the 4th prompt of Mathober 2024:

**and 13th prompt:**

*Form*

*Cyclic Hexagon.***will be using various geometric**

*FlowInGlow***for the visuals and previously coded**

*“Forms”***Composition based on layering/modifying Hexagons post-code.**

*SonicPi*## Poetry

```
Forms
What are they?
What do they proclaim?
Is being in a form a necessary aim?
For yesterday, tomorrow or today?
Forms

## Code

### Hydra Code

```
osc(1,3,1)
.diff(shape(4,1,1)).invert(2).luma(0.15).kaleid(()=> (time % 12) + 1)
.modulateScale(noise(1,0.5,3).kaleid(()=> (time % 12) + 1).repeat(4,4)).out()
speed = 0.15
```

### SonicPi Code

```
#area of regular hexagon
#(3 * Math.sqrt(3) * s**2)/2
def hexagonarea(s)
puts (3 * Math.sqrt(3) * s**2)/2
return (3 * Math.sqrt(3) * s**2)/2
end
def hexagonperimeter(sides)
return sides * 6
end
live_loop :hexasounds do
use_random_seed (Time.now.to_i)/2
#looping the area of hexagons which sides are between 1 and 9
with_fx :distortion, mix: rrand(0.3,0.6) do
use_synth [:piano,:chipbass].choose
play hexagonarea([1,2,3,4,5,6,7,8,9].tick), pitch: hexagonperimeter([1,2,3].choose)
end
sleep [0.5,0.75,1,2].choose
end
live_loop :hexasounds2 do
use_random_seed (Time.now.to_i)/3
#looping the area of hexagons which sides are between 1 and 9
with_fx :echo, decay: dice(3) do
use_synth [:piano,:chipbass].choose
play hexagonarea([1,2,3,4,5,6,7,8,9].choose), pitch: hexagonperimeter([1,2,3].tick)
end
` sleep (Time.now.to_i % 4 + 1)/1.5
end
