London-based company, The Unseen is one of the few companies that has actually managed to launch their product in the market. Their line of products is a luxury accessories line for Selfridges. This accessories line consists of backpacks, scarves, phone cases that respond to things like air pressure, body temperature, wind, touch and sunlight with a change in colour. For instance, a snakeskin shoulder bag will shift its colour to black in winter and red in spring and blue in summer.
