What is sterling fractal?

As an AI language model, I do not have access to specific information about a "sterling fractal," as it is not a well-known term or concept. However, fractals are complex geometric patterns that repeat at different scales and are often found in nature. They have fascinated mathematicians and scientists for decades due to their intricate beauty and their applications in various fields, such as computer graphics and chaos theory. Sterling may refer to the metal or the currency, but it is unclear how it relates to fractals.
