Colourful feathers (A5)

A generative expression of PI along bezier curves. The length and direction of the lines running along the curves are determined by something called eased interpolation. Their rotation goes from ZERO to PI, which means their direction changes by 180 degrees along the curve. Ther is also a sprinkling of randomness affecting the lines thanks to Gaussian Distribution.
