This bangle is a representation of turbulent flow of a liquid over a moving surface. The inside of the bangle -- representing the moving surface -- is smooth, while the outside is curved with the loops and whorls of the turbulence. This is the first in a series of three designs that illustrate the same turbulent flow at different moments in its development. In this design the turbulence has just begun to develop and spread throughout the flow, so there are some turbulent areas with strong twisting and other smoother areas where the turbulence has not yet reached. The second and third designs show the turbulence in more fully developed states and are rougher and gnarlier because of it.
This model is 2.3 inches (59 mm) across on the inside. I'm happy to resize it for larger or smaller wrists; just ask! The bangle is only slightly flexible.
