This p5⁎js sketch Sketch was inspired by Genuary 2026’s “Fibonacci forever” prompt to:

Create a work that uses the Fibonacci sequence in some way.

It animates the Fibonacci sequence¹ , displaying each digit and filling the grid with shapes until reaching the next Fibonacci number. The size and radius of the shapes is controlled by noise values that change over time and the color of the shape is determined by which digit in the Fibonacci sequence it is associated with.

Footnotes
