Amsterdam has a a Light Festival with a walking route that takes you past several light artworks. This one is called "Drawn in light" by artist Ralf Westerhof. The installation rotates above the Amstel River and shows a typical Amsterdam streetview.
This installation in front of the City Hall is a result of a collaborative project between the "New Heroes Foundation" from the city's residents. They collected light bulbs from Amsterdam residents and created an installation in which the light bulbs form the statement "We light Amsterdam" . You can only see these words from above when you go up a special stair in the nearby Music Hall, which we didn't know. So maybe we come back another time to watch it.
This is the lighted famous "Skinny Bridge" with a Big Tree by Jacques Rival and made of colored branches of LED lights, commemorating the many branches of the Amsterdam canal system.
