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.
