Welcome to JC Younger's Project. Golden spiral is a logarithm( logarithmic scale is a nonlinear scale used when there is a large range of quantities. ) and it is a logarithmic spiral which has a growth factor of φ (Phi which is the 21st letter in the alphabet,, also known as the golden ratio. The Golden spiral gets wider by the ratio of φ every 1/4 turn it makes.I advise you to mess around with the red dots and see all the cool shapes the spiral can make. Then after that try to get the spiral back in its original form.
