This video relates our journey to look for order in the chaos of turbulent flows. In addition to being ubiquitous in the universe and central to human existence, these flows are beautiful, largely because they exhibit coherent structures. We think these structures have a deep mathematical meaning that can help us better understand and model these flows. We tell the story of how we found such three-dimensional structures using cutting-edge experiments and how we are just beginning to understand the origin of some of them, an in particular, of the mysterious Loch Ness monster...
