Graffiti Wall is a unique and exciting product that allows the interactive creation of virtual graffiti on a digital wall – a designated rear projection screen, using a laptop, projector and infrared spray cans. As you press the infrared spray can, it emits an infrared light beam, which is tracked by the computer. Then Graffiti software converts the beam into a virtual image that appears on the projector screen known as Digital Graffiti Wall, creating a vibrant and colorful drawing.
