SMS Wall is a digital extension of a Graffiti Wall, but a very powerful extension. SMS wall is the general term for systems that accepts sms messages from the users and then displays them on to a public display. These systems are very social in nature and with a very powerful effect on the crowd sentiments. As part of this system a Projector, LCD display or a Laser display is set up on the floor. The number to which SMS are to be sent is displayed on the corner of the screen at all times. As and when the SMS are received they are queued by the system and then displayed on to the screen.

The manner in which these messages are displayed can be made very interesting to suit the crowd sentiment (Corporate, Party, Soft mood, etc) and can be customized to a branded theme.
