Each piece arrives with its own unique colourway. Twist the shaft and watch the two nuts race in opposite directions along a single rod. Three stacked sections of varying thickness form the body, topped by sharp-edged ridges that taper into a jagged star-shaped perimeter.
Spin the rings along the thread and they glide toward each other until they meet. Turn the shaft the other way and they retreat to opposite ends. The sawtooth top, scalloped middle section, and knurled exterior ridges give your fingers plenty to grip while you track the back-and-forth motion.
Keep it on the desk for those moments when you need something to do while you think. Watching the nuts track along the helical ribbon turns idle waiting into a quick burst of focus. Leave it there and it will keep pulling your fingers back whenever your eyes drift to it.
