Extreme Dominoes

I have always enjoyed dominoes. I have wasted hour after hour stacking just to push one domino over and watch the domino affect set in (lame pun intended).

I can't imagine doing this... it would just be too much work...

And then there's this one, which proves the domino pun...

And since you've watched 3... why not watch one more?

And the Grand Finally... this must have taken a week or two!

Imagine getting to domino number 29,999 then having the whole thing collapse? That would be disappointing... to say the least.
