But competition is likely to be tough. Not only will Wally hunters have to locate his rooftop perch, but they will also have to wait for Google's imaging equipment to pick it up.
Although Google Earth pictures can be up to three years old, the company does not reveal when it plans to update its images.
But, as Miss Coles, 22, insists that's all part of the fun.
She said: 'The goal of the game is to get excited. It's like this huge shift. Radio is going to the Web. Television is going to the Web. And now Waldo is going to the Web, which is pretty fitting right now.
This is what I'm surrendering to the Google god.'
Miss Coles, an art student who has publicised her project on the blog whereonearthiswaldo.com, is now encouraging others to follow her lead and create a series of Google Wallys across the world.
'I think that it's within the spirit of the state of the Web now. Everything is a free-for-all, and I think the more Waldos, the better,' she said.
How brilliant of idea is that? I am surprised someone did not think of it earlier! OK, I am off to find Waldo on Google Earth!
