An electronic kiosk promises art on demand. “At a touch-screen terminal called a Totem, you’d browse for a painting by its name, the artist’s name, or the museum in which it is housed. Works are available from institutions like the Louvre in Paris, the Uffizi Gallery in Florence and the National Gallery in London. Then you’d choose how many copies you’d like to print, at what size and on which medium (choose between 25 types of paper, including canvas and photographic paper). Then go pay the cashier. The Mona Lisa on canvas costs about $30, but larger prints run up to $150.”
