This splendid poster displays many beautiful photographs showing examples of three-dimensional spirals and helices in nature and in the built environment. It also introduces and explains how right-handed and left-handed helices are fundamentally different from two-dimensional spirals and ends by showing how easy it is to calculate their lengths using the Theorem of Pythagoras.
