Graffiti Wall is not just a wall you can tag, it is also a performance installation, when a good artists uses the tool a crowd will stand and watch fascinated by the experience, then we clear the wall and allow everybody to go and try it.

Graffiti Wall is a multiuser interface, we have tested it with more than 10 writers at the same time and it can virtually be done in any size we want.

It was developed for the Richmond Winter Festival. It took almost 6 months to complete and get to a very stable system.
