Skyline Squidarella Collection by Squid London…
SquidLondon is a young innovative company that experiments with color-changing products. Their most notable concept, a water-reactive umbrella that uses hydrochromic inks that change the white part of the umbrella to color when wet. How does it work? Basically (from what I learned from Wikipedia) it works the same way similar existing materials usually react to heat or UV light, but instead, this ink changes color in contact with water. (via)
The psychedelic colours remind me of the Taiko Matsuo-designed stuff for the Shanghai World Financial Centre.
