We've already seen cities turn to technology to combat graffiti
, but it looks like the tables could one day be turned, at least if designer Stefan Rechsteiner has his way. As you can see above, his so-called "Couleur sur l'Objet" robot concept would be able to climb walls (relying on suction, it seems), leaving a trail of graffiti behind it. That would apparently be entirely done using software to plot out its course ahead of time, although we're sure it could also be rigged with a remote control to allow for a little freestyle spraying. Of course, the chances of anyone actually releasing such a bot are pretty slim (at least for graffiti-ing purposes), although there's nothing stopping you from taking a certain DIY-friendly solution
and trying to build your own.
