Project: http://www.instructables.com/id/turn-signal-biking-jacket/

Motivation:

We find this project to be interesting mainly due to its relevance to the course theme.
It is wearable, possible to make in natural materials, wireless (except internally) and could potentially be useful during rush hours or night time.
