Some kind of readable chip that could be included on tombstones that could be scanned to produce any (or all) of the following
1) Your novel (poem, song) that never got published
2) A photograph (later hologram) of you in your "glamour shot" post
3) Your tiresome rant about current era politics
4) Your birding life list
5) A list of your 10 best golf scores, bowling scores, running times
6) The advice you always wanted to give, but no one ever listened
It's possible this already exists. I thought about a patent.
**Edit** I should make clear that I first had this idea in the pre-internet (but post-computer) era, and I know "The Cloud" can handle this. But I still think there is a place for immediate gratification when people are strolling around cemeteries, which is still done. Besides, who is going to look up an unknown name on the web except for genealogical inquiries, unless there is a hook .... "Please visit my photo album at www.___" And what if the dreaded 404 "Page Does Not Exist" comes up? Or a hacker phtoshops your glamour shot? Geez, I'm talking myself out of this, even though I would be dead.
