Stephanie likes to use Math to make her jewelry. These pieces were created using a Python script so that they would repeat a cylinder shape in a spiral. The formula is based on Fermat's spiral (http://en.wikipedia.org/wiki/Fermat's_spiral) and uses the Fibonacci sequence (http://en.wikipedia.org/wiki/Fibonacci_number).
