Have a question for your fellow citizens and wonder how they'd react? We made an art installation for just that! "Vote With Your Feet" is a public installation that asks questions for citizens, and get answers from citizens.
Two doorways stand in the middle of the sidewalk, with a question displayed on a sign above them. Each door stands for an answer. The installation counts the number of people that walk through each door. Once you walk through the door, you can see the results on the door, and online at VoteWithYourFeet.org
The installation was live on Market St during Market Street Prototyping Festival (http://marketstreetprototyping.org/) and had more than ten thousand votes in 3 days. We were excited to see what San Francisco thinks. We're also fascinated if you duplicate them in your city and test it out, so we can compare notes!
The project composes of three major parts:
I. The construction of the door
II. The control of the flipdot display
III. The data logging and visualization
We will focus on Part I in this instructable.
I designed the entire structure on Fusion 360. The design can be viewed and downloaded here http://a360.co/2eyGxnz
Your design will entirely depend on the tools you have at hand, and the budget and esthetics.
