[Video] Cards of Heat & Color

An obnoxious soundtrack is the backdrop to a video of these visually stunning thermo-sensitive cards in action. Developed by France’s edgy design firm Murmure, these cards remain black until touched. Only when handled do the cards give up their information, and do so in a preselected color, transforming these little rectangles into temporary art objects. Guaranteed to be kept and handled for years to come.
