interesting.

I can just imagine sculptures based on Steem, Bitcoin etc... poping up everywhere :)
With, of course, plaques with QR codes to donate in said cryptos too

Hmmm... to go even further some sculptures could function as "physical faucets", containing an internal computer system designd to give out small amounts of currency stored in genrated QR codes on a little screen. with a disclaimer that the currency comes from an external program so no use ripping the sculpture apart for more, of course.

diid I go a bit far there ? hehhe
