Bearing similarities to the Emoto project we looked at over the Summer, Mithru Vigneshwara's Aleph of Emotions uses location-based Twitter information to measure the 'mood' in various cities around the world.
 
 Looking like a traditional camera, the user points the device in any 
direction and, combining the technology of a GPS, a smart phone and 
openFrameworks, the Aleph of Emotions captures and displays the 
emotional state people in major geographical locations.
 
 This is 
another example of technology merging with intuitive design to measure 
or record concepts previously considered too abstract and intangible to 
be turned into meaningful data.
