On Nuit Blanche, Torontoist’ll be lucky enough to claim a spot on one of the biggest canvases of all: the Art Gallery of Ontario’s walls. And we want to share it with you.
Throughout the night, from sunset on October 3 to sunrise on October 4, we’ll be continually projecting updates—photos and text, from both our contributors and our readers—to a big section of the huge south-facing wall of the AGO, just off McCaul Street (which, incidentally, is closed to car traffic that night). At the same time as that’s happening, we’ll be adding some of those updates to a liveblog right here, on Torontoist.
We’re calling it Blanche Slate, and our living wall is part of a larger project taking over the AGO that night: in addition to us, public art advocates BeautifulCity.ca, Eye Weekly cover-stars ArtStars*, and culture fest Manifesto are all claiming a different portion of the building’s exterior; inside, some of the first floor galleries of the AGO will be open to the public for free, until 3 a.m. Here’s our more complete guide to Nuit Blanche’s best bets.
So—want to participate in Blanche Slate and see your deep Nuit Blanche observation, clever Nuit Blanche joke, or brilliant Nuit Blanche photo cast onto the wall of the AGO and preserved for all posterity online? Easy! You’ve got a few options over the course of the night:

• Sending along text? Keep it short—no more than fifty words—and email it to nuitblanche@torontoist.com. If you use Twitter, tweet what you wanna tweet @torontoist. Be sure to tell us where you are: it’s a big city and a big nuit.
• Sending along photos? Email them directly to nuitblanche@torontoist.com, or add them to our Flickr pool. Make ‘em big: to look good on the wall, photos can’t be less than 1000 pixels wide and 800 pixels tall. And, as with any text updates, be sure to let us know where your photos were taken.

We’ll be curating our favourite things out of what we get sent, and—with big bold credit to whoever sends them—throwing them onto the wall of the AGO and into our liveblog all night. So come out, come out, and help us make this year’s all-night contemporary art thing a nuit to remember.
