I was fortunate to be in Brixen Italy during their Water Light Festival. The festival ran from May 9 – 25, 2019 and each night from 9 – 12 PM there were various displays throughout the city center. While they had a map, they also strung green fiber cable above the streets that you could follow from display to display. The highlight were the colorful flying fish that moved to music in front of the Brixen Cathedral.
