This fortnight was dedicated to finding the right honk.

After experimenting with various ways of making a gust of air (bike horn, dog toys, aquarium pump, rubber dust cleaner, balloon pump), it turned out that an electric airbed pump triggered by an Arduino was exactly what I'd been looking for.

The current state of affairs

 

 

It has also been a week to think about the context of the horns. Should they only respond to negativity or could they be an emotional chorus representing the full range of sentiments on offer from sentiment analysis? Surprise, calm, fear, sadness, disappointment, anger and disgust. Also, to what extent should the experience be gamified? Would a longer playful interaction make sense in order to find out what sorts of words trigger a response? 

Possible application - positivity policing in the workplace?
