As reported this week by Gizmodo, a team of bricklayers in Australia invented a clever, if not entirely practical, way to build a wall. What starts as a simple game of dominos ends with an ingenious and surprising twist.
It starts slow, but you'll want to watch to the end.
I'm no bricklayer, but I'd imagine this level of precision spacing (and lack of mortar) makes this more of a fun trick rather than a pragmatic and useful technique. Still, it's fun.
