Review on Kinetic Spring Sculpture: Flow Ring by Herve Latreche

A fun toy, even for adults ;-) It's a deceptively simple shape that will entertain and surprise, and tactile sensations are part of the experience. You can put your hand in the middle and gravity will make it roll down your arm. It can be rolled up into a flat roll, so after a bump it turns into a toroid. I played with it for a while before giving it to my precocious nephew and I hope it stimulates his imagination. Constructed from a single piece of flat, springy wire, smoothly soldered together.
