I think u should make the sculpture of bitcoin icon standing there. It will grab more attention.
That's how I envisioned it. Not laying flat on the ground.
Surely, there's a Bitcoiner with a couple kids under roof residing in some part of the country where there's plenty of snow on the ground. Simply set them up a bitcoin donation wallet address and ship their asses outside to construct the damn the thing. Just make sure the end result is something that'll be admired and not something of just a bunch of snow packed together. They're going to have to take a certain pride in their work if they expect to be compensated accordingly.
