Observe how this Binary Marble Adding Machine by Matthias Wandel of Woodgears.ca works: “When the rocker is set to the left, that represents a zero. When it’s rocked to the right, it’s set to one.”

Watch this for the math, watch this for the math with a paper and pen, or just watch how the marbles fall through the rockers. The video shares fascinating mechanisms no matter what your age or math level is.
