Twists are an essential building block of the universe.
DNA, of course. All strings and yarns and ropes are twists. My favorite pastas, cheeses, and breads are twists.

I have been investigating twists for years now, and I find that twists really illuminate the plasticity that makes hot metal so appealing to me.
Twist and Shout.
