Closing the loop between speakers and audience. Ever wish you could talk back to the speaker at a conference? To offer approval? or register dismay? Use red:green!

A couple of years ago, facilitator Jerry Michalski introduced the concept of “red:green” cards.

These cards are a clear, yet unobtrusive, way to bring the audience into a conversation without having to disrupt the flow of a thought and without having to deal with voting clicker boxes or microphones. They’re a wonderfully elegant way for an audience to give respectful feedback in real time.

red:green is the iPhone implementation of this idea, with the advantage that it can be used in the dark. Just hold up your iPhone while in the audience to display either a red or a green screen. Click on the screen to switch the color. It’s that simple!

We look forward to seeing you at iPhoneDevCamp!
