A conceptual artist named Neil Mendoza has created a combination of gadgetry and software that allows his pet goldfish, named Smashie O'Smasherson Jr, to interact with his surroundings with a robotic hammer. I'm not sure the fish is really in on the joke, but some stuff definitely gets smashed. Here is a link. I've embedded the video below.
Perhaps if several generations of goldfish were allowed to grow up in this environment, they'd evolve some interesting behaviors – I could imagine fish going on smashing rampages when hungry, for example.
Surely with technology like this, our future is bright.
