Tomás Saraceno (born San Miguel de Tucumán, Argentina, 1973) has produced an installation specifically for the vestibule of the Hortensia Herrero Art Centre. It consists of six clouds made up of irregular tetrahedrons and dodecahedrons covered with iridescent acrylic glass, which completely fill this sixteen-metre-high entrance hall. As Saraceno himself explains: ‘Colour stimulates your imagination: these could be soap bubbles floating in this atrium, and then, when you get closer, you see that the work is full of cosmic spiders’ webs inside.’
