The prompt for Genuary 2024 Day 29 is SDF (Signed Distance Function)
Within the SonicPi Composition of "Circular Thoughts", the SDF controls the bpm, rate, beat_stretch and the notes being played
The Circles are Rotating
Their Inner Thoughts are Gyrating
The tone is Glitchy
The thoughts are plenty
As the Circular Thoughts are explaining
What their inner Thoughts are Saying

#getting the sign distance function
#Formula = d(x,y)= Math.sqrt(x**2 + y**2) - radius
#which can be written as Math.hypot(x,y)
#x,y coordinates and the r for radius

Math.hypot(x,y) - r
