As Elsa is creating her ice palace, one line of the song "Let It Go" is "My soul is spiraling in frozen fractals all around". 'Fractal' is the term applied to certain mathematical geometries which have the property that a fractal structure looks the same at all levels of magnification. Snowflakes and other ice artifacts exhibit fractal geometry, and certain artificial fractal objects are nicknamed "snowflakes" because of their resemblance to them. The application of fractal mathematics to computer-generated images was one of the first major breakthroughs in the creation of realistic three dimensional landscapes in computer graphics, enabling films like Frozen - Il regno di ghiaccio (2013) to be made.
