Plutonium: The Contest: "Basically, we want to create a memorial to plutonium, that nasty substance that stays radioactive for thousands of years, it can be made into nuclear bombs, and is deadly if ingested. But hiding it away, as conventional notions dictate, will prevent the world from learning anything from its folly... We're also giving away more than $3,000 in prizes to the person or persons who come up with the best design for our Plutonium Memorial."
