Platinum eggshells a work of art?

(Vancouver, BC) Officials at Canada Place are mystified by the discovery of a number of metallic 'eggshells' in what looks like an ordinary seagull's nest.

"We come upon nests from time to time and there are bits of shell in them, but the weird thing is, these are metal," said Eli Sycazlyk, one of the convention center's maintenance workers. "I thought they were silver at first but they had them examined by a jeweler and apparently they're platinum."

Sycazlyk thinks the shells may be part of an art installation, perhaps as a tie-in to the upcoming Winter Olympics in 2010.
