The Orvillecopter by Dutch artist Bart Jansen (R) flies in central Amsterdam as part of the KunstRAI art festival June 3, 2012. Jansen said the Orvillecopter is part of a visual art project which pays tribute to his cat Orville, by making it fly after it was killed by a car. He built the Orvillecopter together with radio control helicopter flyer Arjen Beltman (L) . REUTERS/Cris Toala Olivare
