"Give me a grande caramel espresso drink with an... image of the Mona Lisa painting on top. No! Make it that picture of me and my grandma at the Grand Canyon. Here, it's on this flash drive."
You wouldn't expect to hear this at your local coffee shop and in fact, you won't, at least not for now. But if you visit Oleskiy Pikalo, you could use his customized Philips 8155 x-y flatbed plotter to print an image on the top of your morning caffeine drink. The latte art printing machine prints like a normal printer, it just uses edible ink.
