Cast your mind way back to your childhood and you’ll remember playing around with inflatable swim rings. In fact, you might not even have to cast your mind back that far to remember them, as you might still enjoy their company when you go for a paddle. While they’re a familiar sight in swimming pools, one place you don’t expect to see them is attached to a wall in the middle of Lyon, France.Travesias de Luz’s Floating Lights installation for La Fête des Lumières 2012 uses the inflatable rings to create an interactive artwork, where members of the public can switch the lights on and off.Consisting of two giant low res screens measuring 10 by 3 meters, they each have 100 colored light tubes that can be turned on or off by touching the switch at their center. The idea is to engage the public of all ages to indulge their playful side, as the collective aim for people to “have fun powering on and off each float and be carried away by their creativity and ingenuity writing messages, words, pictures, or just enjoy the experience.”[via Design Boom]@stewart23rd
