The silo is located outside of Helsinki in Kruunuvuorenranta, a residential area across the water from the city. The neighbourhood's old harbour and terminal were largely abandoned, but a commission from the World Design Capital program brought new life to at least one derelict structure: A 2773m² oil storage tank on the edge of the ocean.
Along the tank's steel shell, a group of designers from the Lighting Design Collective punched a pixellated framework of tiny holes -- each replaced with an LED. Each of these 1250 diodes is controlled by a central computer, programmed to react as the weather outside changes. The steel shell twinkles and shimmers in warm reds and cool blues until 2am (when the last ferry back to Helsinki leaves).
