Every evening in February, the LED façade of the Ryerson Image Centre is animated by a blue wave representing wind speed and direction while an intermittent red pulse is triggered by fluctuations in the use of the hashtag #homelessness on Twitter.
By visiting intheairtonight.org people can read and retweet messages from the Twitter feed or compose their own, and they can watch the building change colours via webcam. They can also donate to various organizations that provide support and advocacy for people experiencing homelessness such as Toronto's Out of The Cold and Raising the Roof. Every message with the hashtag #homelessness amplifies the issue online and contributes to a colour change on the building.
