Tombstone add space

This is a weird idea I had while reading another list, I actually think grave yards are an archaic and weird waste of land. Within a couple generations no one will care who you are or where you were buried. I want to be cremated.
  1. Built in screen with slide show and or videos of the deceased.
  2. You can also sell add space on the screen to pay for the tombstone and funeral/burial expenses.
  3. You can put a website on the tombstone or the screen and the website would be where you can learn more about the deceased.
  4. The screen could be a touch screen so you can watch the slide show or swipe it to look at the persons Facebook.
  5. The family could put the persons favorite app games on the tombstone touchscreen so people can play games on it.
  6. Ok, this is getting weird
