Opal-Inspired Material Changes Color When Stretched http://ifttt.com/images/no_image_card.png

By layering tiny nanospheres onto stretchy fabric, scientists have created a material that changes color when stretched. Called "polymer opal" by the team, the material mimics the multicolored brilliance of an opal gemstone. Now, using ink made from synthetic photonic crystals and a printer that can modulate voltage, the team has figured out how to print shimmering, color-changing patterns onto a stretch of flexible opal.
