Interestingly, I read just this morning about an art exhibit by an installation artist called Marco Evaristti in the town of Kolding in Denmark where the police were called to shut it down for just this reason. The interactive exhibit consisted of goldfish swimming in kitchen blenders. The public could push the button on the blender if they wanted to. Apparently two goldfish had already become bouillabaisse by the time the animal rights people had complained about it!
