The green burials are interesting enough. It would be hard for your friends and loved ones to visit your grave, I suppose, but they could visit the general vicinity.

I've been thinking about this for awhile. I want to have my body submerged in plaster, then have a drill bored into it pass it through a furnace. Then have my ashes removed and cast it in bronze. Then put the ashes back in and cap it off. That way, I could be a perfect likeness statue, ash vessel, and tombstone all in one!

As for location, in the yard or garden would be a great spot. Even after I'm long forgotten, I could serve as garden art and a place for the birds to poop.
