+ Cats and Marble Run...is what the people who posted it have named it. But what you probably don't know is that this a version of a game often played on ピタゴラスイッチ ('Pythagoras Switch')! I even have one of those Pythagoras Switch devices that the cats are knocking the marbles into. Bururu is the tabby and Beruru is the black and white cat.
If you (like me) are mesmerized by these devices, you can see many more at this youtube list (I haven't watched all of them, but I can particularly recommend #1 (which is pretty much like the Switch ones except the camera cuts in some jarring ways) #24, and #25)
And yes, they are basically Rube Goldberg machines.
