The Axiom Broadcaster is a single button video booth where any visitor to the gallery can record a short video of their experience. What is on your mind? The videos are then automatically uploaded to http://youtube.com/axiombroadcaster
and labeled with the time and date. This creates a public history for the gallery and an archive of the views of visitors. When you see the videos online, you can really say "I know where you're coming from."
How do we imagine a device like a public telephone (cheap, ubiquitous, public, easy, many vendors) but instead of making a call to a specific person, it allows you to place a public photo or video online?
