Ouriço is a suspension lamp, designed to conceal within its interior, decorations that can be customized parametrically. A chiaroscuro effect, sometimes sharper and sometimes more nuanced, enhances the decorative pattern. The aesthetic perception that we have of the lamp, apparently minimal with the light turned off, is therefore distorted with light on, transforming it into an alien organism, a marine, organic and pulsating being of fluorescent life.
