Its not Greenwich Mean Time. Its all the emotions

"The Greenwich Emotion Map is a collaborative art project using BioMapping to chart an emotional landscape. Members of the community borrowed BioMapping devices and went for walks. The devices measure Galvanic skin response throughout the walk, and this suggests emotional response along the path of the walk. 'The resulting maps encourage personal reflection on the complex relationship between us, our environment and our fellow citizens. By sharing this information we can construct maps that visualise where we as a community feel stressed and excited.'" [WorldChanging]
