Where Bitcoin meets art, there’s Matthew Groves of California. Paper wallets made from artisan papers by skilled hands, the black magic of BIP38 makes it possible: you don’t have to entrust him with your key, just your encrypted key.
His dragon paper wallet is fairly stunning, but the intricately folded origami pig (with the key folded into the inside) makes me giggle every time I look at him.
Just think of it. It’s a piggy bank which is nothing like a piggy bank, yet works exactly like a piggy bank. It’s not ceramic, it doesn’t hold pieces of metal inside, you don’t have to break it; and yet, it is a darling pig, it does hold coins inside, and you do have to unfold it to redeem it. It’s cute, it’s a great piece of origami, and it’s conceptually brilliant.
That makes it art.
And again, since you generated your own BIP38 encrypted key, the trust required is near zero; if you saved a copy of your encrypted key (as you should), then there is no reason at all not to enjoy this piece of pig-bitcoin-art.
