Possible Crowd-Sourcing Project

So I gave some thought to the idea of doing something on campus, using the student body as my crowd. Why not use something all these student already have in their possession to make art? I thought those new mini clickers that we all had to get were perfect. Why not set up a "room" everyone can log into, which has its signal broadcast across campus, they will be asked a question, like maybe how they are feeling that day, and their answer could correspond to a color. Each time a person logs in to the room, they will be given an incrementally new number, corresponding to a pixel in a picture. Their answer will turn their pixel a different color, and the result could be shown up on a giant screen, making an artwork from the response of the crowd
