The Clicky Track

I marched straight off the smooth boards and hit a giant fuzzy rug! Right along the edge was a stray plastic zip tie, coiled into a perfect spiral like a tiny caterpillar track. I leaned my weight on one end, and snap—it looped into a snug little ring! Pushing it rolled smoothly forward across the carpet weave. It's like my very own mini conveyor wheel, sturdy enough to steer wherever I need to go next!
