When I was young, me and my brother had this game called Domino Rally. You may have also had this game. They may even still make this game.
The title is pretty self-explanatory. We would make Domino courses. Some were extremely elaborate courses we would spend a loooooooonnnnng time setting up just right.
So when they worked it was a joyous occasion.
And when they didn't (one little domino failing to fall and stopping the avalanche) it was heartbreaking.
But our rallys were nothing compared to this.
Prepare to be amazed.
