This movie by photographer Cristobal Palma shows how children playing on roundabouts generate electrical power for three twirling parasols at an installation by Spanish studio Clavel Arquitectos in a Shenzhen public square.
Completed for the Shenzhen & Hong Kong biennale of urbanism/architecture 2011, the lightweight circular canopies reveal their golden undersides when they spin.
