While others have rightly pointed out pollanywhere, I'm looking to go beyond just polls. I have text based discussions and will be adding audience annotations (useful for small meetings, brainstorming, etc) in the near future.
Not really related, but I had another idea (more of an art project) about installing a projector in a public place or maybe on a uni campus that you could text to and have it project your message. Some kind of experiment of uncensored amplification of speech.
