The Oblivion Domino Effect
This reminds me of the good old days in my childhood home, where my brothers and I spent long nights building expansive Rube Goldberg machines with nothing but a Domino Rally playset and some Super Marbleworks. We even had the tripwire which would drop weights from the ceiling, killing cousin Jeff, but launching his body forward, to continue what we called "The Great Pilgrimage of the Bricks."
This is some very impressive editing, however - and probably my second-favorite Oblivion machinima.
