I'm thinking of running tests in a smaller area to see how people react or if I have to rethink this a lot... My aim would be a to find a resonable sized and interesting area and try to map the emotions during a time fram. The former emotional maps that I find vary a lot in terms of mapped area and graphic design.
It might be interesting to make a series of maps, colours or some kind of markings changing according to the mood, and I also like the idea of comments to make it feel more accesible in a way, this is all anonymous but yet the readers get access to very personal thoughts and feelings.
The level of anonymity and feeling of closeness to the people sharing emotions also vary a lot.
