Those who can read French or Dutch or are good language guessers may head over to americanexpressblue.be where you'll find their latest billboard campaign hidden under the giant television set on the flash site.
You may upload an image of yourself and pals, that will appear on the interactive billboard which is on a streetcorner somewhere in Belgium. You can then watch it on the website via a live webcam, and once you have been on the board you get an image sent to you in the mail that you may pass on to pals. Playing on everyones wish for 15 minutes of fame one can have a lot of fun with this billboard, but please, don't send the goatse image..... (Actually, I already did, the images are filtered for content before they go live. Had to test that.)
