In a collaboration with SGI and the University of Illinois' CyberInfrastructure and Geospatial Information (CIGI) Laboratory Kalev debuted the first-ever realtime combined population, tone, and geographic analysis of the live Twitter Decahose (10% of all tweets globally), creating a realtime map of global dreams and fears. Over the course of the annual 2012 Supercomputing conference we displayed both live global and US maps of emotion on Twitter in realtime in the SGI booth and on its website, updated once per second, using a 256-core 4TB RAM supercomputer, the first time all of these dimensions were ever visualized of a social media stream in realtime. Additional movies were created to show Hurricane Sandy and the 2012 US presidential election as viewed through the eyes of Twitter.
