We know how much fun it is to topple a row of dominos. What’s not so fun is picking them up again, or even worse, stacking them upright again. Could someone design a machine that does that? That would be pretty complicated, because dominos may fall in exact lines, but they end of on the floor in a jumbled mess. Grant Davis not only made a machine that can reset dominos even when they misalign, he made it entirely out of LEGO parts! More than 4,000 LEGO pieces, which took him between 300 and 400 hours to conceive, design, and build. It picks up dominos, stacks them in alignment, and topples them, too. -via Gizmodo
