[yfibqmwy] press F to pay respects IRL

create a tombstone featuring the letter F, inspired by gaming.

for example, the F could take the place of the cross often prominently carved or incorporated into Christian tombstones.

more ambitiously, the F could be shaped like a button, suggesting people touch it.  (not actually a button because moving parts are fragile.)  perhaps it gets worn down over time if many people visit the grave and touch it.  a tombstone that invites an easy way for people to interact with it is a significant improvement over traditional tombstones.  it is vaguely like a tombstone with built-in vase that invites people to interact by leaving flowers.

the bronze statue of "John Harvard" has a worn-down foot where many people have touched it.
