A Brood of Rube Goldberg's Spawns!

Okay, okay.  So what if we like following how balls knock things down? We like other things too.  Like how dominoes knock things down.  And we really like how dominoes knock each other over and make all the pool balls go in the pockets (please pardon the intro...)
