Building a Plutonium Memorial

edsonw writes: "The Bulletin of the Atomic Scientists is giving $3,000 in prizes in a contest which will select the better ideas about how to handling and storing plutonium.. In their words, "We're inviting artists, architects, and general visionaries to submit their artistic work for what we're calling the "Plutonium Memorial," a facility that would house the world's unwanted weapon plutonium. We see the memorial, were it actually ever to be built, as a grand and visible emblem reminding the world that short-sighted paths to power can lead to a big pile of problems"."
