Canadian artist Melanie Coles has painted a 55-foot image of Wally on an undisclosed rooftop in Vancouver, British Columbia. The game now is to figure out where Wally is and to be the first to spot him when he eventually turns up on Google Earth. It's a game of chance because the company does not reveal how often it updates its images, and it doesn't take its own satellite images in the first place, it licences them from a third party.
Coles publicised the project on her blog www.whereonearthiswaldo.com, and is encouraging others to follow her lead and create a network of Google Earth Wallys across the world.
