It seems that the robot coffee-froth-art baristas are on their way, though not quite yet in kitchens on the High St. Once the bots are proven in the chain coffee shops and have a central database of latte art designs to choose from, could chains then have a curated “artist of the day”? With the artist’s various designs having a tiny URL integrated into them? If the customer likes the art, simply typing the URL into their device would transfer 50 cents to the artist’s PayPal account. If they don’t want to donate, they just sip it down. Alternatively, grumpy art-hating curmudgeons could pay a little extra to get a normal plain old-fashioned coffee.
