DeadSquare

Deadsquare is the morbidly convenient way for you to keep your friends updated on your whereabouts. Just post a photo of yourself dead, and friends and potential mourners are immediately apprised of your location. You can also unlock made-up badges and mayorships, and then award them to yourself any time you want because, what the hell, you're dead.

Post to deadsquare.net, Facebook, Twitter and Tumblr all with one upload.
