245 732, that's a lot of dominos!
That was just amazing, I can't wait to show my sons. Master 6 loves lining things up and Master 4 loves to watch them come crashing down. Mr 9 will go nuts for the science and math involved in creating such a fantastic piece of domino art.
I see some domino creation days in my future. On a much smaller scale I hope.
Thanks for sharing.
