I like that you keep asking even if it is half assed. :)

I've had an idea for an AR game like Pokemon GO but you mine your crypto IRL.
An added feature would be to let players deposit info/treasure at spots in the real world.

Then anyone can make a treasure hunt.
This is a four year old dream and unfortunately I just don't have the know how.
I did make some sweet AR gallery apps though.
i.e target one picture to get surrounding images that tell a story.
