Wonderbra in Belgium have used the Google Maps API to create this 'find the difference' game using photographs of some scantily dressed women. The game presents two photographs of a woman in a Wonderbra and asks you to find seven difference in the photographs.
Using the Google Maps controls you can zoom in on the details in the photograph and if you don't become too distracted you might actually find the differences. If you spot a difference just click on the map and a map marker will be added.
There is an iPod Nano, some Wonderbras and some gift vouchers to be won!
