When the Spanish light artists at Luz Interruptus installed and illuminated 800 condoms filled with blue water, they chose a politically charged location. A square in Madrid that previously housed a public swimming pool had been closed two years earlier by local politicians. Even worse, new plans to develop the square into a tourist market would take the space from locals completely. To reference the need for community recreation, and the history of the square, the artists designed and installed an interactive sculpture called "Prophylactic rain that doesn’t wet anything" with the help of a few local kids.
