Instructions

See different patterns of Fibonacci spirals. Tilt to get different views. More dots (Christmas lights) increases resolution (but may lower Christmasiness)

Description

My first try was in 2D: https://scratch.mit.edu/projects/615164630 To make 3D, I tried a golden angle sphere. Then I changed my golden angle sphere project into a cone. All these models are based on golden angle turns, 1.6108.... of a turn, spaces dots out creating Fibonacci spirals, as do pine cones, pineapples, and many flowers. Transparency allows additional interplay between spirals. The slider variable is multiplied by the angle, so resulting color relates to the golden angle turns. Music: "Christmas Prelude" performed by the Concert Band of the United States Air Force Band of Mid-America. Track 1 from A Musical Christmas (2007). Public domain (and available on Wikimedia.com)
