An interactive light tunnel installation called ‘Hundreds and Thousands’ allows visitors to change the light colors. The tunnel was built at Vivid Sydney 2013 to inspire hope in people who view it. Built by Designworks for The Benevolent Society, the tunnel gives people by getting them to tweet their aspirations. Tweeting with the hashtag #hopesforchange makes the tunnel change colors. The more people hoping, the more varied the colors become.
Benevolent Society is a non-profit organization that helps people through education and other forms of support. The installation aims to further that end by asking people what positive change they want to see in Australia. The catch is that the hope should be achievable in the next 200 years.
