This ceiling lamp, available in 8 models, is a play on optical illusions. Impressions of apparently finite geometries, formed by transparent glass elements alternating with others in opaque white shaded in the colour of yet other components which, instead, allow practically infinite designs to be developed. In fact, the four available linear models can easily by placed side by side in a personalised sequence, to form semi-transparent, illuminated walls. LED light sources are fitted in the opaque elements, to prevent them from being seen, while LED spot lights are embedded in the ceiling structure, illuminating the wall from above. Another four models feature a circular structure, with differing diameters and lengths. LEDs are included with all models.
