Hey Guys!

The dominoes are assembled using a python script which itself creates a MASH Network. The coloring uses a MASH Color Node, where only one face is actually colored due to the other five being made of arnold surfaces. The dominoes start their movement thanks to a long cylinder which knocks the first column down, but I made that cylinder invisible for the video portion.

The python script itself only sets up the dominoes and the cylinder, setting up the camera and playblasting the whole thing was done manually after the fact.
