Foscarini's Blob, created by industrial designer Karim Rashid, is a collection of freeform table, floor, ceiling and wall luminaires. The largest version, which is 49.58 in. by 19.75 in., can be used as a luminous seat or display shelf. All models share an elongated, softly curved, translucent polypropelene light diffuser. Illumination is provided by twin-tube fluorescent lamps.
