SpirallingGraph

For this week's Creative Code challenge by Raphaël de Courville :" Spiral ”, SpirallingGraph is Coded in Python, SonicPi & Hydra.

Poem

To get past
Into the land that vast
Sustaining motions that can be able last
Be hold , for the times
That we take a pause
To rewind
Where does the Spiral act false?
