A free, all-night art party took over Winnipeg on Saturday.

Nuit Blanche invites the public to take-in art created by local architects, filmmakers, painters, in an effort to make art more accessible and interactive.

One installation included a giant cloud of light bulbs on display at the base of the Esplanade Riel, on The Forks side for the official Nuit Blanche Winnipeg kick-off.

The showcase turned the Exchange District, downtown Winnipeg, and St. Boniface into public art spaces.

Dance parties in vacant lots spilled out onto streets. Winnipeg Police Service officers were out and monitoring the scenes, but no major incidents were reported, a police spokesperson told CTV News.

The annual Rainbow Trout Bike Jam brought together hundreds of cyclists to take a winding path through the downtown. People decorated their bikes, while sound systems pulled by pedals pumped out the music.

Displays and showcases ran through the night from 6 p.m. to 4 a.m.

Nuit Blanche began in France in 1984 and has grown to be an international contemporary art movement.
