The“KataKraK” company, created by Sandra Sardà, builds interactive installations, which allow people of all ages to play the leading role. Sandra’s work has three guiding principles: Creativity, Recycling, and Play. We have a workshop full of found objetcts, old machines, industrial and domestic appliances and house-hold objects. We work the materials, sculpting it into a participatory and exceptional game. We use public space available for our installations and covert plazas, parks and sidewalks into play spaces. The active participation of the public is essencial to our project.
