Just sort of messing around today with a bunch of different simple premises - technology/bitcoin as art, hiding private keys in plane sight, adding value to art through bitcoin, etc - and came up with this. It's really just a proof of concept, but imagine this hanging in a gallery. In this case, admirers could donate to the owner from their smartphone by simply taking a picture of the piece. But, on top of that, the private key to the bitcoin address that the piece represents
is in the piece itself and there are even some hints in the peice to locate the private key.

Anyway, maybe it's a stupid idea.
