Canadian artist Melanie Coles built a large image of the iconic "Waldo" onto a rooftop at an undisclosed location in Vancouver, British Columbia, Canada.
The image was intended to be later searched out through interactive mapping applications like Google Earth and Google Maps.
Check out my blog article on this subject, Where's Waldo in Google Earth.
I got this photo from Melanie Coles' sister's Flickr set, Where's Waldo in Vancouver? Check out the additional shots she has on the construction and such!
FYI - a key relevance of this is that Where's Waldo is known as Where's Wally outside the US.
SPOILER: I have placed this image onto a map here in Flickr, pinpointing the building's location in Vancouver where the building with the image is located. While you can view the satellite image of the building now, it will be some months before Yahoo! Maps has updated the images -- so, it will be a while before Waldo is visible in the online map. To view the map, click on the "(map)" link found to the righthand side of this description, under the "Additional Information" list in the sidebar next to the text "Taken in Vancouver, British Columbia". -->
