Some of our eagle-eyed city-goer followers may have already spotted this joyous installation which has emerged at the Leadenhall Building. Named Evanescent, this iridescent bubble-like installation has been created by Sydney-based design studio Atelier Sisu. At 7.5m this is a larger-than-life installation and visitors can walk under it, around it and watch the colour change from cyan blue to magenta pink in the light for a fully immersive experience.

True to its name (meaning the state of being impermanent and fleeting) Evanescent will be on display at the Leadenhall Building for just one month, until mid-February. Whether you work in the City of London or are just visiting, be sure to catch it before it is too late!
