Mini Fin Sin Fin is a compact, illuminated sculpture based on the large-scale Fin Sin Fin installation, whose name means “end without an end” in Spanish. This smaller 3D puzzle structure is composed of oval aluminium composite panels connected through a modular plug-in system. By day, the panels absorb sunlight, activating fluorescent and phosphorescent pigments that glow in the dark. At night, additional UV lighting enhances the piece with a soft purple hue, bringing its glowing surface to life. Though smaller in scale, Mini Fin Sin Fin retains the spirit of the original—its rising form sparks curiosity, and its modular design allows for endless reconfiguration, as long as a 90-degree angle is maintained. Adaptable, sustainable, and visually engaging, the sculpture has also been presented in interactive settings where visitors could use laser pens to draw with light directly onto its surface.
