So, Jason Allemann of JK Brickworks made a LEGO machine that perpetually knocks down an infinite ring of dominos. It’s a useless contraption, but I could stare at it all day, and I’m sure you could too. Jason Allemann is a well-known LEGO builder with decades of awesome projects under his belt.

And Allemann has designed some official LEGO sets, like the popular LEGO Ideas Marble Maze. Anyway, Allemann’s Infinite LEGO Domino Ring features a circle of 64 red dominos, which perpetually fall in sequence and stand back upright.

As a result, the robot can knock down about 1,500 dominoes each minute of operation. (Allemann plans to do a one-hour test of this machine to see how much it can endure.) Notably, this project was inspired by Grant Davis’ auto-stacking LEGO domino machine. Unlike the crazy ring we’re looking at today, Davis’ machine operates in a straight line an… Click below to read the full story from How To Geek
