Ted Kinsman, an assistant professor of Photographic Arts & Sciences at RIT (Rochester Institute of Techonology), has created a printer that prints images using drops of liquid.
The printer can print using liquids like coffee (see below), blue ink-coloured water, and cheap red wine.
The printer can print up to 4000 drips per hour – or about one drip a second. Watch the video below to see the printer in action.
