A couple of years ago, Jerry Michalski introduced a number of people to the concept of "Red:Green Cards," which are described thusly:
Ever wish you could talk back
to the speaker at a conference?
To offer approval
or register dismay?
Use RedGreen feedback cards.
I found the concept to be absolutely fantastic. It was 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 those little voting clicker boxes or microphones. It was possible to achieve this goal without any kind of intrusive hardware at all, actually.
Red:Green cards are a wonderfully elegant way for an audience to give respectful feedback in real time.
At the iPhoneDevCamp last year, Biggu built a prototype of the Red:Green voting concept for iPhone. However, it appears that their implementation has been taken down or is no longer working. (The site was throwing errors the last I checked.)
So, we (re)built the Red:Green iPhone app from scratch. You can find it here:
uses the Mobile Safari orientation hacks from the Apple code samples,
so it only works on the iPhone. If you go there from a desktop
browser, it’ll just show a blank page.
- Concept inspiration from Jerry Michalski.
- Code inspiration from Nicole Lazzaro and the TILT iPhone game.
- Implementation adapted from the Apple iPhoneOrientation sample.
- Address bar hiding hack from Christopher Allen.

iPhone-friendly network/directory of female political bloggers. Currently,
there are over 100 bloggers listed from all sides of the aisle. Here
are the coordinates if you are so inclined:
