— TetraBIN explores how digital technologies can be used to motivate positive change in urban environments. It employs game mechanics and game thinking to turn depositing rubbish into a bin into a joyful event. Reminiscent of 8-bit era video games, TetraBIN allows players to collaboratively control light blocks on the screen. The prototype features a custom-produced and manually assembled screen consisting of 900 LEDs mounted onto laser-cut Perspex and covered with a translucent layer of polycarbonate. Project team: Steven Bai, Sam Johnson, and Martin Tomitsch. Exhibited during Vivid Sydney 2014 and at the Robots, Fabrication & Design exhibition in the Faculty of Architecture, Design and Planning at the University. Further details are available on the TetraBin project website and TetraBin is now also available as a commercial product via Sencity. Photos by Steven Bai and Martin Tomitsch. Video by Steven Bai.
