What is it about?
When twisting starts, the deformation is the same everywhere - a simple helical shape. But at higher twists, an amazing range of new shapes are possible, essentially due to different ways of buckling, and to geometrical constraints. This paper explores some of the conditions for different shapes.

Perspectives
Before being involved in this work, I was quite unaware that such a simple set-up could give such rich behaviour. I found it to be a fascinating problem, both to understand and to quantify the conditions for observing the different morphologies. And much remains to be done.
