With the Ripple Maker you can turn all your selfies into Latte art. Using patented printing technology, the machine creates inspiring Ripples from any image or text atop the foam layer of coffee beverages. By syncing with the Coffee Ripples app on your iPhone or Android phone, the machine makes high-resolution images. Since it is fully Wi-Fi enabled, Ripple Maker receives image selections to its interface and prints in coffee scale, which is like gray scale but caffeinated. Proprietary Ripple Pods are packed with a concentrated coffee extract, so the machine interprets any image or message into a version that can be printed using the extract as a sort of ink.
