Third places are social places like coffee shop and bars, where people come together to catch up with friends and meet new people. Our research explores how Ubiquitous Computing experiences in public space, particularly interactive public displays, can be leveraged to encourage interaction between strangers. We present a multi-display application based on the metaphor of a table-top community garden. This application is built using our Really Easy Displays (RED) framework, a set of web based technologies that allow the rapid development of applications that span multiple displays, sensors and actuators. The prototype makes use of a situated large screen, a projected surface and an Arduino microcontroller to support collaborative interaction, by allowing groups of people to collectively nurture a table-top garden by interacting with furniture, touch-enabled projections and mobile phones.
