Sergio Sebastián Franco, with a studio in Zaragoza, was inspired by the bells of the Monastery of Sant Cugat del Vallés to design temporary lighting pieces that produce different effects combining refractions, shadows and transparencies. Almost 6 meters high, the metallic structures are supported on inclined legs. The space generated between them envelops visitors, offering them both day and night plays of light in its different models, from the Xylophone to the Kaleidoscope, through a reinterpretation of the church rose window.
