Polska gola! is an example of a "shadow fence". On a sunny day a shadow fence casts custom shadows on the ground in front of it, depending on the time of the day. Polska gola! is made of laser-cut metal sheet with manually bent elements, and displays via shadow the "Coca-Cola" logo in the morning, and a popular Polish soccer-cheering phrase "Polska gola!" in the afternoon. It has been designed for Lodz Design Festival in 2012, and manufactured by Zieta (dimensions: 280cm x 120cm, resolution: 86px x 50px).
