Gruppo MID developed the Stroboscopic Structures which consisted of a surface with circling lights that spun rapidly when the viewer pushed a button in the centre. At the time, however, technical restrictions prevented the artworks from reaching their full potential. The group continued to exhibit internationally until 1972 when they parted ways and pursued successful individual creative careers. In 2000, Barrese and Marangoni re-established the collective, partly driven by the renewed interest in the Op and Kinetic Art movement that continues to date. Advancement in technology allowed the artists to realise their original vision and they commenced the process of restoring their historic works using programed motors, power inverters and LED lights. Disco Stroboscopico, presented at Puerta Roja in Movement (2018), is a prime example of a work originally conceived in 1968 and reconstructed in 2012.
