The light installation celebrates the London 2012 Cultural Olympiad in the north-east of England. The Global Rainbow has previously lit up the skies of Germany, France and the United States. The projection will shine along the North Tyneside coastline for 4 days, before moving to other locations in the UK. Several researchers warn that some kinds of LiDAR could harm the human eyes and cause damage to autonomous cameras that are used for safe operation. Aside from these, this innovation could also damage the cameras used in professional photography, smartphones, and traffic devices.
