YrWall is an interactive digital graffiti wall that allows users to spray invisible infrared light from a modified spray can onto a large screen to create digital graffiti designs. The digital paintings appear on the screen just as real spray paint would on a wall. YrWall events have been used by companies like Virgin, NatWest Bank, MTV, and Volvo for promotions, team building, and charity events. Users can customize designs, messages, or artwork and have their creations projected onto buildings or printed onto items like debit cards.
