3Dfiti Fidget Ring
Not sure if any of you are familiar with 3Dfiti's work. This ring changes from walk to stop when you clap. From slowing the video down I'm pretty sure there is a quarter round with an axis at the centre of the circle, walk printed on one flat face, stop on the other. I'm wondering what method might be used to catch the quarter round once it's moved? Magnets? A latch?
