- 6. LIVE Singapore! Provides people with access to a range of useful real- time information about their city by developing an open platform for the collection, elaboration and distribution of real-time data that reflect urban activity. Giving people visual and tangible access to real-time information about their city enables them to take their decisions more in sync with their environment, with what is actually happening around them. http://senseable.mit.edu/livesingapore/
