This year was not the first in which the City Hall of Toronto was lit up in a unique way. However, it was the first time that the government building was used to project 4-letter words. Brainchild of [D.A. Therrien], the 4LWM represents something that he imagined for a long time. [Therrien] built the huge sign in Scottsdale, Arizona, where he displayed it over the waterfront. He was later commisioned to bring the sign to Toronto for Nuit Blanche after making some adaptations (due to weather differences). The sign is composed of 4 huge 16-segment displays. Each segment is made of many neon light modules. This configuration makes it less noticable if one such module fails. The sign is controlled below from a computer, which allows it to display text and simple animations. It’s the first in a series of installations dubbed ”Beautiful Light” by [Therrien]. Despite the name, no inappropriate language was displayed on the sign.
