From performance art to the atmospheric, sound art to visual installations, Nuit Blanche is an event that grows in popularity in many cities each year. Taking place literally all night, people can wander from one side of the city to the other observing, experiencing and even participating in art exhibitions ranging from secret subway tunnel vibrational drones, giant grasshoppers taking over a park, a post office where you can send a postcard to a stranger in the future, giant webs of stretchy string, and impromptu "house parties" with live bands set in public parks.
