Textile designer Yun Ding has created Aqua Chameleon, a line of delicate-looking swimwear printed with smart pigments such as thermochromatic and photochromatic ink that change patterns based on certain conditions. The patterns gradually shift from a geometric print into a decorative pattern by reacting to temperature, sunlight, or water conditions. These "swim costumes" challenge our notion of how a garment should function aesthetically by adding dynamically changing patterns based on the changing environment around us and displaying it back for all to see.
