This colorful structure is called the Synchronicity island and has been constructed in Warsaw, Poland. It is actually a water treatment plant that utilizes human energy in the water purification process. The structure is fitted with exercise machines which when worked upon makes the pumping of the polluted river water into four filters, then to four tanks and then finally to a fountain basin.So all that workout looks doubly fruitful, making both you and your environment beautiful!

Designed by Jakub Szczęsny of Centrala, this was built for the architecture and art festival in Warsaw.
