Usually when an artist finishes their work, they sign it. Graffiti artists are no different. However, with graffiti being illegal and all, there’s a cool and rebellious sounding term for the way that artists uniquely sign their graffiti.

It’s called ‘tagging,’ and graffiti artists are often referred to as ‘taggers.’ So it’s no wonder that an app, which allows you to ‘graffiti’ the side of a building, goes by the name TagTool.

TagTool is an iPad app released at the end of last year that allows users to create graffiti on their tablet, and then project it onto the side of buildings with light.


Created by Vienna-based company OMAi, TagTool replaces spray cans and paint markers with an iPad and projection mapping system. Users have the option of ‘painting’ with their fingers on the tablet screen, as well as the ability to incorporate a touch animation system to further bring their creations to life. The visuals can then be streamed onto a building, or any surface of your choice, displaying an interactive light show.




TagTool also allows users to collaborate with another creator over Wi-Fi, allowing a joint creation or real-time show.

From the company’s past blog comes this description:

Finger-painting together with friends is incredibly satisfying. It made us think of cave people gathered around a fire, using the walls to share images from their experience and imagination. In the 21st century, the medium of choice is light, and the paintings are alive.

Projection mapping has become an increasingly popular tool among advertisers for unexpected outdoor advertising, as can be seen by here, but it still requires expensive and bulky equipment for the most part. This app, which would require little more than an iPad, projector, and power source, could revolutionize the whole art of projection mapping displays.


OMAi believes their new app is very easy and intuitive to use, comparable to finger painting, helping inspire art and DIY creations. We doubt that Banksy and other graffiti artists would approve of TagTool, but what about the authorities? Graffiti is illegal because property is being defaced, but what about light pollution and public disturbance? Much of the projection mapping that goes on in advertising uses preapproved sites, and those that don’t tend to face repercussions for their ‘guerilla’ tactics. We’d be careful before you start projecting your creations onto just any old building, but TagTool is definitely an interesting manifestation of the digital age adopting an old-school art form.
