In design news, Thomas Heatherwick unveiled a glassware collection for gin brand Bombay Sapphire that is made up of glasses and sculptural bottles.

The collection comprises two hourglass-shaped bottles, the largest of which contains "a terrarium of sorts" for the display of botanicals found in Bombay Sapphire gin.

Also in design, British artist Alex Chinneck unveiled a series of distorted street furniture to bring "surrealism into the public realm".
