Anyone who claims they've never fantasized about their own funeral is lying. It's not a morbid fictionalization, it just is. We don't particularly want to die, we just enjoy envisioning all the posthumous glamour -- the exuberant eulogies, the mourning ex-lovers, the sentimental speeches. We might be celebrities after death! Great writers! Artists! Living fame is tacky.
Over My Dead Body is the new design company capitalizing on that very fantasy. An offshoot of the artist's collective, Smorgasbord, OMBD works with folks while they're still alive to concept and design their very own customized tombstones. So, no, odds are you can't plan your own funeral. You can, however, manage the creative direction on your grave site.
Once you contact the company, the team will work with you to sketch out your vision, before either designing your headstone themselves, or liaising between you and another artist who can better carry out your mock-up. Once the memorial is completed, you can take a look, but the studio will continue to store the thing until you croak, at which point they'll deliver it to your next of kin, who is hopefully still alive.
