The Golden Spiral
This animation draws a spiral based on the Fibonacci sequence, a series where each number is the sum of the two preceding ones (1, 1, 2, 3, 5, ...).
- The spiral is constructed from a series of connected quarter-circle arcs.
- The radius of each arc is a number from the Fibonacci sequence.
- This pattern appears frequently in nature, from seashells to spiral galaxies.
