working on it…
We used a plain QR code canvas to accept bitcoin donations at the cryptovalley conference in the Isle of Man for a local charity (then gave them the cash as they do not accept bitcoin (yet)).
They were initially horrified I had messed up their QR code (which just takes you to their website) - had to explain that a QR code could be more than a website link and calm them down first!
Became more interested when I pointed out paypal wouldn't take 8% of donations, they could track donations so thefts almost impossible, plus donations could be made anonymously which might lead to extra funds from people wanting to be discreet/ private...
Just had a 'branded' canvas delivered for a major UK charity that does accept bitcoin (will post a picture here, hopefully after they approve it)
Part of Satushi's plans involve using a % of any profits to design and deliver canvases to every charity that does accept bitcoin
Digital file is more useful as charities can put them on Twitter/ Facebook/ LinkedIn etc to make donations as easy as possible, but we think CrypArt is still useful for events/ office receptions etc
