Sorry if you had time to read this before I edited, I'm new to this.
If you are not aware what a Rube Goldberg is, here's the explaination: It's a overly complexed machine powered by the domino effect to do a simple task.
It's pretty much the same machine as in the domino save.
Only this is mine and I built it myself.
Anyway, sadly it's really not that big.
I hope you can forgive me for that and if not...
Just imagine the guy in the end of the course is me =D
(and it shouldn't be that hard to realize that you shoot the flower pot next to the big text saying "START" to start the machine)
