What is going on in India? What do people talk about in South Africa? Hello World gives you a sense of that – browsing the surface of a globe lets you access the Top 10 Trending Twitter tags for different locations.
Talking about different representations of space for browsing local information, we were intrigued by globes: rich associations, tactile memories of tracing a globe´s surface with my fingers and wondering what is going on in all those places.
Hello World is the result of a 2-day prototyping project at UID in collaboration with Clayton Cook and Siri Johansson. We used Arduino to access the display and a RFID reader, and Processing to read the Twitter API.
