This is self-explanatory along with the video itself. An artist uses a laser which he could use to paint graffiti on buildings in a distance. With this type of technology, it wouldn’t be surprising to one day see the disappearance of billboards and posters for street advertising. The laser in this video is operated by hand, however if this could ever be automated, this can possibly be a very efficient tool for displaying entertainment on advertising along a cityscape.
