A Million times at Changi is a functioning clock that I encountered at Changi Airport after visiting Singapore for vacation that represents the concept of time. This is not only a clock but also a kinetic sculpture that was developed by Humans Since 1982, which is a Stockholm-based artist collective, in 2014.
This art piece is made up of 504 clock-faces with hour and minute hands that have been programmed to spin in various directions to create a series of synchronized designers and patterns that change multiple times throughout the day. It represents the abstract concept of time passing by while also reporting real time.
