Loop is a system of prefabricated modules for the configuration of skateable bowls of small, medium and large dimensions, easily assembled without the need for heavy concrete work. Loop is a unique urban landmark that unites the sporting spirit, the social and aggregative function of a discipline born "on the street", with the world of art, design and architecture. An object capable of living differently depending on the time of day. For this reason Loop represents a way of understanding art and design in public space that is very close to the tradition of "playgrounds" which has so strongly marked the history of public space design since the late nineteenth century. The possibility of customisation through street art interventions (contests), the lighting system (with the possibility of interaction), the sculptural forms that perceptually evoke architectures, and finally the aggregative flexibility, make Loop an object easily placed in any urban context.
