Once you set up dominos and let them fall… that’s it. But what if they could continuously get back up? Enter JK Brickworks’s infinite LEGO domino ring, built with 64 constructed dominos, a ramp that runs along the inside of the ring to lift the fallen dominos back up, and a LEGO Mindstorms EV3 in the middle of the ring to regulate the ramp’s speed so the dominos rise and fall at the right time. A fine piece of engineering.
