I saw a piece this evening on Current TV, the Goggle digital TV channel. They did a ‘pod’ piece on the SMS Guerilla Projector and it’s application, not only for commercial purposes, but also street protest and the like.
I have seen projectors used to project imagery on public buildings, and this does seem an interesting progression.
The SMS Guerilla Projector is a home made, fully functioning device that enables the user to project text based SMS messages in public spaces, in streets, onto people, inside cinemas, shops, houses…
Small, portable, and battery operated, the SMS Guerilla Projector contains a mobile phone which enables the device to receive and project messages from other people.
The SMS Guerilla Projector is made by recombining available technologies. As an open object, the projector generates a wide range of applications, allowing the user to display messages and share his reflections.
Its unpredictability creates a very special and disturbing experience for the people who watch the projection, and invites them to reflect on the content or the implications of the message.The images below show actual examples of projected messages.
